Weird Characters appering in the browser
My company's product help file is generated in WebHelp, but
on the web I see in some pages showing some weird characters. When
I checked my source file as actually what characters are they in
the file, I see that the trademark signs (TM) , single quotes, and
double quotes are appearing as a ? inside a diamond. I went through
the script generated by Webhelp and see the character set Webhelp
is using as charset=windows-1252, Can't we change it to UTF-8 so
that its a universal character set and is recognize on all
platforms and browsers.
Please let me know if there is a solution.
Thanks,
Ashish
UTF-8 is the norm with RH7. If you cannot upgrade, or do not
want to, take a copy of your output and try changing it manually in
one topic. If it works then use a multi file find and replace tool.

Keyboard produces wrong/weird characters
Hi,
I have a 2010 13" MBP, running 10.8.x. The keyboard has suddently started throwing out all sorts of weird characters instead of the expected alpha-numeric set.
If I plug in an external USB keyboard it's ok.
It happens in all apps where key entry is used, not just Safari
Is this a stuck 'alt' key or similar?
Thanks in advance for advice
PaulThis is what happens to windows, and that is why Apple is much better, the only problem with apple is that their computers are pricey, and most programs in the world is for windows. But Windows is just problem after problem, for example, my Windows XP Pro (In the bottom in green ) died from scandisk, now I am using my friend's 8 year old laptop because of this reason. Windows ME is slow, and cant do anything. So the main point I guess is that, why install Windows leaving your Mac prone to virises, spyware, and other problems, just stick to Mac, and your life is as simple as can be. No crashes, no problems such as this is in a Apple created environment such as OSX.

Why has my use of the apostrophe started inserting a string of weird characters on my iPad?
My iPad has recently started replacing the apostrophe with a string of weird characters (something like &39; or similar) when I post a comment on Facebook or YouTube. Why is it, and how do I get rid of it? Anybody know?
(The apostrophe appears as normal when I'm still typing; it's only when I send / transmit the the post that it appears.)On the other hand if you want to fix it, it's a simple as going here:

and starting a chat session to get them to reset your activations. -
Weird characters before the xml start tag on Host
When we load xml generated in Biztalk into an OS/400 Host environment, they always have some weird characters before the declaration (<?xml) causing the host program to fail. The characters look like gibberish from another planet (not really..look like
some binary encoding). Can one of the experts please point me to what must be changed?If you look at the message using a hex editor, the UTF-8 BOM (Byte Order Mark) is EF BB BF, if you are using Unicode, the BOM is FE FF or FF FE (depending on little or big Endian encoding).
If you "Stop" your send port and run a test, you can view the suspended message body in hex and determine if these characters are a BOM.

I have FF and win7. Fonts turn to weird characters at more then 75% zoom when the checkbox "allow webpages to choose their own fonts" in the contents option > advanced is checked, when forced to calibri this behaviour doesnt occur
An aexample of that is the product title on the product of this website:
https://www.xstreetsl.com/modules.php?name=Marketplace&file=item&ItemID=2424553
While switching to double check this I just saw that this also happens in this very window in wich i am typing my question now. If i copy and paste this text to for example notepad or anything else, it shows up like normal text.
== This happened ==
Every time Firefox opened
== i installed firefox on win 7This issue can be caused by the bitmap version of the Helvetica or Geneva font or another (bitmap) font that can't be displayed by Firefox in that font size.
Firefox can't display that font in the specified size and displays gibberish instead.
You can test that by zooming out (View > Zoom > Zoom Out, Ctrl -) to make the text smaller.
Uninstall (remove) all variants of that not working font to make Firefox use another font or find a True type version of that font that doesn't have the problem. -

A possible cause is a problem with the file places.sqlite that stores the bookmarks and the history.

Correct display of characters in the Browser - Pls Help - Urgent
Hi,
We have a java application running on solaris 8 connected to oracle 8.1.6 database. The database characterset has been changed to WE8ISO8859P15 to support Western European Characters and the Euro symbol.
The problem we are facing is, when the euro symbol (Alt + 0128) is entered thru the HTML form and then retrieved from the database and again displayed on the HTML form, it shows as inverted question mark or some other character.
If any one can tell us exactly the steps to follow overcome this problem, it would be of great help. What settings have to be changed in the webserver, database and the client side so that there is proper data conversion.
Immediate response is apprecited.
ThanksCouple of samples to try:
1)
<%@ page contentType="text/html;charset=ISO-8859-15" %>
<HTML>
<HEAD>
<TITLE>Hello</TITLE></HEAD>
<BODY>
<%
String charset = response.getCharacterEncoding();
%>
<BR> encoding = <%= charset %> <BR>
<%
String nameValue = request.getParameter("euro");
String euroVal = "\u20ac";
if (nameValue == null || nameValue.length() == 0) { %>
<FORM METHOD="GET">
Please input your name: <INPUT TYPE="TEXT" NAME="euro" value="<%=euroVal%>" size=20> <BR>
<INPUT TYPE="SUBMIT">
</FORM>
<% }
else
nameValue= new String(nameValue.getBytes("ISO8859_1"), charset); %>
<H1> Hello, <%= nameValue %> </H1>
<%
//insert nameValue into database
%>
</BODY>
</HTML>
2)
<%@ page contentType="text/html;charset=ISO-8859-15" %>
<HTML>
<HEAD>
<TITLE>Hello</TITLE></HEAD>
<BODY>
<%
String charset = response.getCharacterEncoding();
request.setCharacterEncoding(charset);
%>
<BR> encoding = <%= charset %> <BR>
<%
String nameValue = request.getParameter("euro");
String euroVal = "\u20ac";
if (nameValue == null || nameValue.length() == 0) { %>
<FORM METHOD="GET">
Please input your name: <INPUT TYPE="TEXT" NAME="euro" value="<%=euroVal%>" size=20> <BR>
<INPUT TYPE="SUBMIT">
</FORM>
<% }
else
%>
<H1> Hello, <%= nameValue %> </H1>
<%
//insert nameValue into database
%>
</BODY>
</HTML>We have tired your code and here are the answers to your questions:
1. Does the euro example work in your environment?No it is not working.we could not run the second example because'
we don't have a "request.setCharacterEncoding(charset)" method.
we are using servlet 2.2 api
2. Is the HTML form a JSP/Servlet or a HTML calling CGI?we are having HTML/JSP form calling a servlet.
the results and forms are always JSP.
3. Try using a HTTP GET in the form and observe the URL on
the browser. Does it show the parameter as:
http://host:port/euro01.jsp?euro=%A4
Euro symbol's code point is A4 in ISO-8859-15. We'd like to make
sure it is not corrupted when it is sent to the server.your previous example shows it as %A4 but it is not inserting correctly
in the database.The ascii value of the inserted value is 191 but we guess the correct
ascii value is 164.
4. After insertion, check the value on the database server.
Assume you insert the data in the following table:
create table tab01 (col01 varchar2(100));
You can query the euro code point:
select dump(col01, 16) from tab01;
Check to see if the value shows A4.the result we have is Typ=1 Len=1: bf
5. Please be aware that the example above is for varchar/char
column. You mentioned uploading blob content into database. Is
it a separate issue? Or do you just request a blob example?Actually blobs are not a problem. What we actually meant is that we are uploading some blob content into the database for which we have to use com.oreilly.servlet.MultipartRequest. But inserting euro symbol becomes a problem when we use this. If we use without multipart request we are able to insert euro but will not be able to upload blob. Blob content is not related to euro.
6. If problem still persists, I suggest that you send us a simple
program of yours that include the HTML/JSP and your schema
(SQL). Here is the program we are using to test.
<html>
<HEAD>
<title>Charset Test</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-15">
</head>
<body>
<form name='f' action="CharsetTestJSP.jsp" method=post enctype="multipart/form-data">
<input type=text name="TestValueMpr">
<input type=submit value="Submit for MultipartRequest">
</form>
<form name='forn' action="CharsetTestReqJSP.jsp" method=post >
<input type=text name="TestValueReq">
<input type=submit value="Submit for OrdinaryRequest">
</form>
</body>
</html>
this is the html file with two forms , one with multipart request and the other without it. When used the form without multipart request, inserting euro into the db, stores it correctly and displays it correctly when retrieved. The html form calls 2 jsp files which are as follows:
CharsetTestReqJSP.jsp
<%@ page contentType="text/html; charset=ISO-8859-15" %>
<%@ page import="com.interactive1.kf.Config,java.sql.*"%>

//java.io.PrintWriter out = response.getWriter();
String test = "test";
String testFromForm = request.getParameter("TestValueReq");
* Here instaed of the test value we are
* inserting what is coming from the form
Connection con = null;
try {
con = Config.getInstance().getConnection();
StringBuffer sql = new StringBuffer("INSERT INTO x_temp VALUES (?)");
PreparedStatement pstmt = con.prepareStatement(sql.toString());

while(rst.next()) {
out.println(rst.getString("text"));
rst.close();
pstmt.close();
} catch (SQLException se) {
out.println("problem sql exception : " + se.getMessage());
} finally {
if (con!=null) {
try {

} catch (SQLException se) {

out.println(response.getCharacterEncoding());
out.println("");

Weird characters sometimes appears on Japanese website
Hello there,
I have a macbook pro. When I go on some Japanese websites, there're full of weird characters sometimes appears. It doesn't happen everytime. How can I fix it? I appreciate your time in advance.bonybunny wrote:
Here's one of example of the site http://www9.ocn.ne.jp/~zennsaku/syasinn.htm for you to see what I meant.
In that case the author used obsolete software from the 1990's to create the site and omitted the required code to tell the browser to use Shift-JIS encoding. -
Weird characters visualized by all webbrowsers
Hi everybody,
I have recently installed OSX 10.6.4 upgrading from Leopard. Installation was successfull but from that very moment on I have experienced problems in webpages' visualization:
common characters such as letters or punctuation marks are often replaced by striped, accented or otherwise weird characters (e.g. "a" has become "ą").
I commonly use Firefox (3.6.8) where many webpages are almost illegible.
On the contrary, Safari (5.0.1) and Camino (2.0.4) are affected by the same problem but the number of 'modified' characters is much smaller than on Firefox; curiously I have not found any match yet between the characters misread by Firefox and those misread by Safari or Camino (that is the characters not properly visualized by Firefox are correctly visualized by Safari and Camino and viceversa).
Furthermore, not all webpages seem to be affected by the problem for e.g. apple.com, wikipedia.com and others are visualized properly. The problem affects appearently indistinguibly all components of the webpages such as buttons (e.g. "Search" on google.com) and input fields of webpages (but not those of the browser or of plug-in toolbars ecc.).
Now, how am I supposed to solve the issue?
Thankyou in advance for helpIndeed the problem concerned (I am happy I may use the simple past) fonts but deleting the font database was not a possibility in my case (I have more than 1.000 fonts and use them everyday so even saving them and reinstalling one by one would not have been of help). Fortunately Font Book validation procedure has highlighted the problem (dued to doubled font packages).
Thankyou for the hint! -
Whenever I am using Firefox, when I am on a webpage (any webpage) & I either click on a link in that page, start typing in a box, click on a button, or click on a tab, the browser window either reduces to the toolbar, or just changes size, usually from full-screen to 2/3 of its size. I reinstalled Firefox (downloaded from the web) after wiping my hard drive because I was having so many problems from my browser constantly crashing, to the computer itself crashing often, to the computer running exceptionally slow. At first everything seemed fine. But then after having opened my computer a few times, a few different windows began to freeze, then that stopped, then this thing with the browser started a few times later after opening it. Now it does it every time I open it. Also, whenever I try to click on a button on other windows on my computer, I get the 'warning' sound, nothing happens, then after a couple more tries, the button works. All of this is just weird. I had antivirus protection on my computer, but it apparently did not catch whatever virus infected my computer, or the damage was already done when it did get it. I thought once the hard drive was wiped, that everything would be ok, but then these weird things began to start up, and now I am wondering.... Of course, it could also be something wrong with the browser, too. I've also had some trouble getting my printer to working again, but I've managed to solve that problem.
I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6. -
Offline approval - weird characters in Outlook
Hi all,
We're on SRM 5.0, Server 550, SP12.
Scenario: offline approval of Shopping Carts
After running report RBBP_NOTIFICATION_OFFAPP, approver is getting an e-mail in Outlook 2003 with some weird characters:
**START**
Â
   The following requires processing:
Â
   1 . Approve shopping cart of Shopper with value 64,78 USD
  Â
Â
Â
   Use the following link to log on to the system and carry out the approval online:
   Log on
Â
Â
   To approve or reject directly from this e-mail, select one of the following links:
Approve by E-mail  Reject by E-mail  Â
**END**
When I look at the same message in , these characters are not visible; but there seem to be spaces/blanks in those spots. Looks like Outlook is substituting spaces for some other character.
Also, there're some extra blank lines, which we would like removed.
Any ideas how to get rid of the unwanted characters and unnecessary lines, besides BAdI implementation?
Cheers,
SergueiHi,
Please check the foll note:
Note 1100912 - E-mail messages for work items with incorrect line break
Also,sometimes some junk characters are inserted into the offline mail if the required services(for the generation of mail ) are not active in transaction SICF.
Please see whether the following path is active in SICF:
SAP/BC/BSP/SAP/SMART_FORMS/DEFAULT.CSS
If the above service is not activated,then activate that and re-test.
Last option would be to implement the BADI BBP_OFFLINE_APP_BADI (method ~MAIL_DATA_GET) to remove the unwanted characters.
BR,

Error in sending a binary outputstream to the browser
I am looking for information on sending a binary outputstream to a browser.I am not getting any error and am able to write out the entire buffer.Even though the browser recognizes the mime type,it only sends junk to the client.Please look at the code sample below that I am using to send the outputstream.
response.setContentType(MimeType);
String str_encoding = response.getCharacterEncoding();
System.out.println("================= The Character Encoding is --------------" + str_encoding);
int len = buf.length;
System.out.println("Data length ===========" + len);
response.setHeader("Content-Disposition", "inline;filename=" + "\"" + fileName + "\"");
OutputStream o = response.getOutputStream();
int buffer_length = 10 * 1034;
int offset = 0;
//read a thousand bytes from the buffer at a time
while ((offset <= buf.length) && (loop==true))
if ((buf.length - offset) < buffer_length)
buffer_length = buf.length - offset;
loop = false;
System.out.println("---------Now Inside the Loop, Writing Output Buffer ------" + offset + " bytes");
o.write(buf,offset,buffer_length);
o.flush();
offset = offset + buffer_length;
If anyone could tell me what needs to be done to successfully send a binary input stream from a Java application to a JSP page calling it and then successfully sending the outputstream for the client to be read,that would be fantastic.yes,I did.That sends the data out as junk.The outputstream gets some sort of junk characters with the response.getOutputStream() method.So it errors out when I set the content length.
I tried sending the data as a whole,but does not seem to make a difference.I was grasping at straws when I tried to break it into chunks. -
Chinese not displaying, unless encoding is set explicitly in the browser ?
Hi,
Our application is working fine at my work place, end user is able to see our application either in english/chinese/malay based on his laguage choice. But in some client place chinese is not being displayed, unless they set encoding to GB2312(Simplified Chinese) explicitly in the browser.
They are not able to see our application in chinese, unless they set encoding explicitly in the brower, in all their systems(Computers), where in different vertions of Internet Explore including 5.0,5.5,6.0 installed.
Even they installed some fonts namely, Arial Unicode MS, and SimSun, this problem is not get rectified.
The characterset is UTF-8 in our JSPs.
Could you please tell me the solution for this problem ......
Thanks in advance
SrinivasHi,
And For one page, we compare the 'View Source(HTML)'
of both ends pages, it is different.....why..?
In these HTML pages, obviously some unreadable characters are
there(which represent Chinese characters). That unreadable characters are different in
both pages, one is created in our end, and other is
created in my client place.
is the problem in browser or server (Weblogic 5.1)?
Thanks in Advance

Yesterday I extracted the subtitles of an MKV file to try and print them. Unfortunately, when I open the .srt file with any text processor, it displays weird characters like the ones included in the title:
"–û–±—ã–≤–∞—Ç–µ–ª–∏ –ø–µ—á–∞–ª—å–Ω—ã.
–í–µ—Ç–µ—Ä –ø—Ä–æ–¥–∏—Ä–∞–µ—Ç –¥–æ –∫–æ—Å—Ç–µ–π."
I thought this had to do with it being an .srt file, but just now I encountered the same problem with an Excel file.
Any ideas why this might be or suggestions as to how to solve it?
Thanks in advance,
MarioIt looks like an encoding problem. You should try opening the file in a text editor where you can choose one of the various possible cyrillic encodings (utf-8, koi8-r, iso-8859-5, win-1251, MacCyrillic)
