Replacing Special Characters With Its Actual Value

Hi All,
Does anyone has any idea how to replace an extended character (ASCII value ranging from 128 to 255) to its actual character set in SQL/PLSQL?
For example: “½” needs to be replaced to “1/2”
“¼” needs to be replaced to “1/4”
Ultimately if the value is “California 71 ½ ” then the result should be “California 71 1/2”.
Thanks for your time!

--Extended ASCII (ISO Latin-1):
á     #225
â     #226
ã     #227
ä     #228
å     #229
æ       #230
SQL> select regexp_replace('á,â,ã,ä,å,æ','[[=a=]]','a') str from dual;
STR
a,a,a,a,a,a

How to replace special characters with html code characters automatically?

A colleague and I work on these html pages. They eventually end up as emails, but we have the cold fusion server to pre process them. One thing we are trying to do is eliminate problems caused by unencoded copyright, trademark and smart quote symbols.
How could I create an array of find / replace commands in the header so it processes the HTML with correct character codes.
I"m not cold fusion aware, so any kind of starter info would be great. Eventually I might add more replacements to the array.
As an example TM (font character) would process to ™ and a smart quote or apostrophe would process to a straight one. an en dash character would become –
Because we copy paste from places, this often happens and it seems like cold fusion could solve the problem quickly and repeatedly all at once.
thanks for any help

CF has a built in HTMLEditFormat function for handling < & > characters. For handling trademark and smart quote characters you might try searching for a user defined function at http://cflib.org or writing a user defined function yourself that will handle the specific characters needed in your application.

Replace special characters in FDF

Hello,
I have searched everywhere and cannot find the answer to this simple problem. I can manipulate javascript in an HTML environment by using free scripts, but it's not so easy in a PDF form. I am using Adobe Acrobat 9 Pro and I have a form that when filled out and submitted, generates and emails an FDF file. I am using a server-side script called FormGenie to do this, and the script hates parentheses and some other special characters, they break the FDF file. All I want to do is set up a document level Javascript that will check for and replace all instances of these special characters with something allowed like a hyphen- or just a space.
I have tried:
function clearText() {
     document.formname.fieldname.value=filterNum(document.formname.fieldname.value)
     function filterNum(str) {
          re = /\$|#|~|\%|\*|\^|$|$|\+|\=|\[|\]|\[|\}|\{|\;|\"|\<|\>|\?|\||\\|\!|\$/g;
          // remove special characters like "$" and "," etc...
          return str.replace(re, "-");
and
function clearText2(str) {
stringName = stringName.replace(/\$|#|~|\%|\*|\^|$|$|\+|\=|\[|\]|\[|\}|\{|\;|\"|\<|\>|\?|\||\\|\!|\$ /g,'-');
I know these aren't right, but I have to be at least barking up the right tree.
Can someone help?
Thank you

OK, here is my first stab at putting together this script from searching the API reference.
To loop through the text fields and get their values, I have:
for ( var i = 0; i < this.numFields; i++) {
var fname = this.getNthFieldName(i);
if ( fname.type = "text" ) f.value;   [Not sure if "f.value" is correct or legal here]
If this is even getting close, where I get stuck is how to get the original script to take those values and replace any unwanted characters found.
if (!event.willCommit) {
    event.change = event.change.replace(/[\$\#\~\%\*\^\+\=\[\]\{\}\;\"\<\>\?\|\\\!]/g, "-");
I just need to put this together correctly and I don't know how.
I have the form submission part down, that was already done, I just need to add the custom "Run a javascript" item above it so that is executed first.
Need a little guidance,
Thanks

Looking for, and replace special characters

Hi
I am quite new to AppleScript and can't figure this out. Any help would be appreciated.
I have received several (a lot of) folders containing images with some strange characters in the file names. The images has to go to web, and I want to replace those characters with some that are web friendly. The characters in question is some Swedish A's and O's (Ä, ä, Ö, ö) and one that looks like the Apple Command symbol. (I was told this one is a combination of a and e).
Then, I would like to replace all spaces between the words in the file names with an underscore.
In addition, all image file names start with capitals and I would like to replace these as well.
Thanks

Replace special characters in xml to its HTML equivalent

Hello All,
I did a small xml processor which will parse the given xml document and retrieves the necessary values. I used XPath with DocumentBuilder to implement the same.
The problem which had faced initially was, i could not able parse the document when the value comes with the '&' special character. For example,
<description>a & b</description>I did some analysis and found that the '&' should be replaced with its corresponding HTML equivalent
& So the problem had solved and i was able to process the xml document as expected. I used the replaceAll() method to the entire document.
Then i thought, there would be some other special character which may cause the same error in future. I found '<' is also will cause the same kind of error. For example,
<description>a < b</description>Here i couldn't able to use the replaceAll(), because even the '<' in the xml element tags was replaced. So i was not able to parse the xml document.
Did anyone face this kind of issue? Can anyone help me to get rid of this issue.
Thanks
kms

Thats the thing about XML. It has to be correct, or it doesn't pass the gate. This is nothing really, seen it many times before. It becomes funny when you start to run into character set mismatches.
In this case the XML data should have either been escaped already, or the data should have been wrapped in cdata blocks, as described here:
http://www.w3schools.com/xml/xml_cdata.asp
Manually "fixing" files is not what you want to be doing. The file has to be correct according to the very simple yet strict XML specifications, or it isn't accepted.

Dwm special characters with tty font?

Currently, I have dwm configured like so:
http://i.imgur.com/JsTurIO.png
But as you can see, in the upper left corner, my tag names aren't displaying properly, neither is the title of the directory I'm in (†††). I've tried the dwm-pango patch, but then I'm unable to get it to use the same font it uses currently for the menubar, which I would like it to do. I also have no idea what the name of the font it's currently using is.
So, two questions: is there a way I can get special characters to show up with dwm while maintaining the same font, and if not, how can I switch the font in my terminal windows so that I can match the statusbar and my other windows? I suspect the answer to the second is just some line in .Xresources which I can probably figure out unless there's something more complicated, but I'd rather just use the same font I'm currently using, but fix the special characters problem.

Edit: Managed to figure this out. But it's still not using a console font in dwm. How can I get it to use a font from /usr/share/kbd/consolefonts/?
I'm trying to also get this to work but get the same error as you did.
How did you do to fix it?
You need to add a couple lines to config.mk in the source directory.
@OP: It's not entirely clear what your goal is. The XFT patch allows for unicode .ttf fonts, and affects the entire statusbar; the current Pango patch allows for fonts in languages with unique character sets (Cyrillic, CJK, Thai, etc.) but some Pango features only affect the right-hand statusline. If you're trying to add, say, symbols or icons to your tag names for a little eye-candy, you can use the XFT patch and use unicode characters. If you're trying to use a font for your native language, Pango would be the better choice. From what I can tell (C often doesn't come easily to me), it seems each patch replaces console font support entirely for its respective alternative. I'm not aware of any solution that could allow you to use a console font in DWM while displaying special characters; you'll probably have to pick whichever patch you feel is less invasive and detrimental.
EDIT: If you choose to apply a patch and then change the fonts in your terminal emulator, the latter depends on which terminal you're using. The wiki has articles on Xterm and Urxvt; other terminals will either have a configuration menu or file you can alter, probably mentioned in the man page.

How to replace special characters in Purchase order item text in ECC 6.0

i used replace_string FM also.it is also not working.
please help me out in this. points will be rewarded.

Hi Praveena,
what replacement(s) did you try?
Please
replace all occurrences of
CL_ABAP_CHAR_UTILITIES=>newline
CL_ABAP_CHAR_UTILITIES=>cr_lf
CL_ABAP_CHAR_UTILITIES=>form_feed
CL_ABAP_CHAR_UTILITIES=>horizontal_tab
CL_ABAP_CHAR_UTILITIES=>vertical_tab
CL_ABAP_CHAR_UTILITIES=>backspace
CL_ABAP_CHAR_UTILITIES=>minchar

Replacing special characters from xml document/text inside element

Hi
Is there any way to replace the xml codes to special characters inside an entire xml document/ for a text in element.
I want to get the xml codes to get replaced to respective special character(for any special character)
Please see the sample xml xml element below
<Details>Advance is applicable only for < 1000. This is mentioned in Seller's document</Details>
Thanks in advance .. any help will be highly appreciated.

So, just to be sure I understand correctly, you want this :
<Details>Advance is applicable only for < 1000. This is mentioned in Seller's document</Details>
to be converted to :
<Details>Advance is applicable only for < 1000. This is mentioned in Seller's document</Details>
If so, I'll say again : the resulting XML document will be invalid.
Extensible Markup Language (XML) 1.0 (Fifth Edition)
The ampersand character (&) and the left angle bracket (<) MUST NOT appear in their literal form, except when used as markup delimiters, or within a comment, a processing instruction, or a CDATA section. If they are needed elsewhere, they MUST be escaped using either numeric character references or the strings " & " and " < " respectively. The right angle bracket (>) may be represented using the string " > ", and MUST, for compatibility, be escaped using either " > " or a character reference when it appears in the string " ]]> " in content, when that string is not marking the end of a CDATA section.
Ask whoever "they" are why they would want to work with not wellformed XML.

Hi

Special Characters in a Node Value

Hi,
I have a node value which contains special characters (ex: it contains degree *°* between the text). When I am adding this text value to a node i am using the following code,
elementVariable.appendChild(documentObject.createTextNode("*node text value with different special characters*"));
How to handle these special characters, because when I open the generated XML file in Web Browser it is displaying an error when parsing this text value which contains the degree symbol.
Does anybody know how to handle this type of text values. If any one had links related to this, please send me.
Thank You.

Thanks for your reply DrClap. What you said regarding posting the query without understanding the code is correct. But I am not expert in XML and I didn't worked on it previously. I suddenly got the request to implement this in our application and i don't have time to learn, so i did some search and found the below code and used that in my program.
It worked for all the types of data, but it is failing only for the degree character (*°*). Could you please check the below code and tell me where I am doing wrong. I really appreciate your help.

Replacing 'special' characters

Hi all,
I was wondering if thers is a function module, class (method) or whatever (codepage translation) to convert 'special' characters like:
è, é, ë, ï, etc with respectively e, e, e, i?
More generally speaking we need to convert all characters (whether it be Unicode, Latin-1, etc.) to plain text containing only the letters of the alphabet from a-z and A-Z.
Kind regards,
Micky.

@ Rainer,
both thanks a lot for your relevant replies which are quite helpful. And I do think that we still needs some sort of intermediate table to hold at least some characters to be translated/converted into plain text.
@ Gautham,
I'm currently testing this function module with several codepages (parameter INTER_CP) beside the default codepage 1146. For characters like ë and ï this is definitely the way to go, but when using some characters that are really out there like ¥ŖßÞu0152u03A9u03C6, we still seem to be needing an intermediate table to replace these characters.
But again, some very helpful answers.
P.S. Although both answers are potentially worth 10 pts, It only seems fair to give you both the credit you deserve.

Replace special characters

Hi,
I want to rename files containg special characters in a directory tree.
For example I want
06\ --\ Doppelgänger.flac
renamed to
06\ --\ Doppelganger.flac
I have found a python script that seems to be able to do it here.
I have also found a list of replacements characters
my $AccentedChars = '€–‚ƒ„…†‡ˆ‰Š‹Œ–Ž––''""•–—˜™š›œ–žŸ'.
'–¡¢£¤¥¦§¨©ª«¬-®¯°±²³´µ¶·¸¹º»¼½¾¿'.
'ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞß'.
'àáâãäåæçèéêëìíîïðñòóôõö÷øùúûüýþÿ';
my $NonAccenChars = 'E-,f,.++^%S_O-Z--````.--~Ts_o-zY'.
'-!cLoYlS`Ca_--R-`+23`uP.,10_qh3_'.
'AAAAAAACEEEEIIIIDNOOOOOxOUUUUYTS'.
'aaaaaaaceeeeiiiidnooooo%ouuuuyty';
from this perl script (which throws an error when used. Otherwise it would be perfect).
So, can somebody tell me how I could feed the python script with the above replacement table?
I have tried but I can't seem to get it to work.
I have also tried to make a simple bash-script using rename but I could not that to work either.
I would really appreciate any help.
Thanks,
Rasmus

I didn't try the perl script, but sed's y command will do exactly this. tr complains about a dash
accent='€–‚ƒ„…†‡ˆ‰Š‹Œ–Ž––''""•–—˜™š›œ–žŸ–¡¢£¤¥¦§¨©ª«¬-®¯°±²³´µ¶·¸¹º»¼½¾¿ÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõö÷øùúûüýþÿ'
nonaccent='E-,f,.++^%S_O-Z--````.--~Ts_o-zY-!cLoYlS`Ca_--R-`+23`uP.,10_qh3_AAAAAAACEEEEIIIIDNOOOOOxOUUUUYTSaaaaaaaceeeeiiiidnooooo%ouuuuyty'
echo '06\ --\ Doppelgänger.flac' | sed "y/$accent/$nonaccent/"
So you could do something like
for file in *; do
mv -v -i -- "$file" "$(echo "$file" | sed "y/$accent/$nonaccent/")"
done
