Unicode diacritical character

hello, i've been trying to figure out how to get a q-hat character (i.e. a q with a circumflex). the "combining diacritical marks" unicode page gives the unicode value of \u0302 for the circumflex, and the value of q is \u0071.
i've been searching all over the place, but i can't figure out what i'm supposed to do in java code to get the combined character. this might be the sort of thing that is so obvious that nobody explains how to do it, but i'm lost...
can anybody help me?

From my own experiments, Java doesn't handle strings that contain "combining characters" properly. My guess is that this is because the procedures for drawing the strings out are a bit simpleminded (one Character = 1 glyph on the screen). In order to get them to display properly, you have to "normalize" the string, which means to combine the base character and combining character into the proper font character. IBM has Unicode software in the ICU for Java (ICUj ?) project that will do string normalization.
The problem you're going to have is that it's possible that certain combinations of base characters and diacritical marks may not have a "combined form" that is defined in Unicode. (Which is why they introduced the concept of combining characters to begin with.)
I don't know about "q-hat" specifically - you could check the code charts at Unicode.org to see if there is a "combined" form for that character and use that.

'Zero-width Non-Joiner' Unicode Control Character for Xperia International Keyboard in Persian

I use Xperia International Keyboard in Persian (Farsi) on my Xperia Z3 Comapct. I really like its Gesture input for Persian. On the other hand I like Google Keyboard for Persian for its 'Zero-width Non-Joiner' Unicode Control Character key.This character is used in Persian as a non-breaking space or "نیم‌فاصله". But Google keyboard lacks gesture input for Persian. I would like it like very much If there is a ZWNJ (U+200C) key on next updates of Xperia International Keyboard for Persian. It would be perfect if it also have Arabic Decimal Separator (٫) (U+066B) and Arabic Thousand Separator (٬) (U+066C).

Remove unicode control character

hey, so i've asked this around a few places and recieved no answers, but the arch community seems like a bunch of smart people and i've recently switched over from ubuntu.
is there a way to remove input methods and unicode control characters from the context (right-click) menu? i've searched and searched, but i've had no luck with this.
there's a way to remove it in gnome with gconf, but i've tried that, and no luck.
i'm using openbox, and i think i found something about my gtkrc file along these lines
gtk-show-input-method-menu =
gtk-show-unicode-menu =
both are "gboolean" which i don't know what it is, or if this is even what i want.
any help would be appreciated, as i never use these menus.

U+2415, SYMBOL FOR NEGATIVE ACKNOWLEDGE is not a control character. It is a normal symbol character, which is a substitute display character used when the control character U+0015 NEGATIVE ACKNOWLEDGE is to be displayed instead of being interpreted.
You need to refine your question.
In general, you can remove any particular character or characters from a string using the SQL functions TRANSLATE or REPLACE. You can use CHR or UNISTR to encode characters that you cannot enter from a keyboard. You can use REGEXP_REPLACE with POSIX character classes to remove broader ranges of characters.

Unicode (numerical) character conversion

What is the problem?
Some characters written in unicode format do not get transformed to their appropriate font-character.
Example
Numerical version: ≥ is printed as ≥
String version: ≥ is printed correctly
Both have the same unicode, yet LiveCycle DS will only convert the "string"-version and not the numerical version.
Question
Is there a way to make LiveCycle convert the numerical unicode representation of special characters aswell? If so how do I do this using LiveCycle Designer. I am working with textFields
Workaround
I have written the following workaround in my java project, obviously I'd appreciate it if I LC did this work for me as I'm not willing to implement a full-scale unicode table while LC has it by itself already (≥ works ...):
private String getNodeText(NodeList nl)
if (nl == null){
return null;
if (nl.getLength() == 0){
return null;
String unescapedString = StringEscapeUtils.unescapeXml(nl.item(0).getTextContent());
return (unescapedString.equals("null") ? null : replaceUnicodeNumbers(unescapedString));
private String replaceUnicodeNumbers(String unescapedString) {
return unescapedString.replace("≥", "≥"); // I changed this code to something more usable

Hi everybody !
Can someone solve this for me. I have a varchar2(9) variable, var, with the value '1234'.
Now I want to convert this to having leading blanks, ie. ' 1234'.
How to do this?
If I use the to_char(var,'fmt') function I get some error message that says there's too many declarations of to_char. I guess because tha variable already is a varchar2.
Thanx in advance

Unicode: Trademark Character

How would I get an applet to display the superscript TM unicode character?
This is what I tried:
JTextArea text = new JTextArea("Widget/u2122");
text.setEditable(false);
JOptionPane.showMessageDialog(null, text, "About",
JOptionPane.INFORMATION_MESSAGE);
Under Windows 2000, I get a square box instead of the TM character.

Under Windoze 98 I got the same thing. When I run the
same program under Debian linux, I get the trademark
symbol. I suspect that the difference is that under
Windoze, my default encoding is ASCII, but under linux
I'm using ISO Latin-5.

Easiest way to create a string with a unicode supplimentary character

In my code I had previously been declaring some strings such as:
String s = "\u1234";Now I have gotten to a point where I want to use a supplimentary unicode character like this:
String s = "\u12345";This, however, does not work since Java only allows for characters in the range: 0000 - FFFF.
I've been reading over this whole codepoint thing in the Character docs but I'm still confused. What's the easiest way to make a string that contains the unicode character U+12345 (just an example number)?

This article here:
http://java.sun.com/developer/technicalArticles/Intl/Supplementary/
says <quote>For text input, the Java 2 SDK provides a code point input method which accepts strings of the form "\Uxxxxxx", where the uppercase "U" indicates that the escape sequence contains six hexadecimal digits, thus allowing for supplementary characters.</quote>
I believe it is referring to Java 5, although I don't see where it says that. However if you are dealing with supplementary characters it might be a good idea for you to move to Java 5 because of its improved support for them.

Problem in replacing with the unicode equivalent character ?

Hello,
I have a situation wherein i must replace
m with \u3005
n with \u3006
o with \u3041
etc ...,
I get the codepoint value from the multibyte represenation .
But the problem is
I can not replace
String temp="ename";
temp.replace('m','\u3005');
I am not allowed to hard code the value 3005, rather i am suppose to get the code point value from the multibyte representation.
I have no problem in getting the code point value from the multibyte represenation.
After i get the code point value i must concatenate the codepoint value with "\u"
Currently i am following this implementation to do the replacement,
String rp=null,snd;
String tmp="ename";
String hh="";
for(int i=0;i<tmp.length();i++)
snd=getCodepoint(tmp.charAt(i));
if(snd!=null)
rp=replace(String.valueOf(tmp.charAt(i)),
String.valueOf(tmp.charAt(i)),"\\u"+snd);
hh=hh+rp;
else
hh=hh+String.valueOf(tmp.charAt(i));
//The replace method
public static String replace(String source, String pattern, String replace)
if (source!=null)
final int len = pattern.length();
StringBuffer sb = new StringBuffer();
int found = -1;
int start = 0;
while( (found = source.indexOf(pattern, start) ) != -1)
sb.append(source.substring(start, found));
sb.append(replace);
start = found + len;
sb.append(source.substring(start));
return sb.toString();
else return "";
Please tell me how to do the replacement
Because when i display after the replacement is done i get
e\u3006a\u3005e for the string "ename"
where as i should be getting special characters in place of 'm' and 'n' in the string
or i must atleast get e?a?e for the string "ename"
Please do offer some suggesstions in this regard
Your suggesstions would be very useful
NOTE:
I am not suppose to make use of the method replaceAll( ) to do the replacements
Thanks and regards

IDOC unicode issue (character #)

Hi
A user exit fills posting items in SAP HR payroll posting with a text in russian language. This value is stored correctly in table PPDIT.
We have different ALE target systems in the distirbution model for different company codes.
All the RFCs are configured like UNICODE with logon language. Two targets system has russian company codes.
The first one is a SAP ECC system and receive correctly the data.
The second one is a SAP PI system and checking IDOC segments text was converted with # . Table EDID4 contains value #.
If we customize IDOC for employee master data HRMD_A russian texts reach correctly into SAP PI.
We unknown if the payroll posting process converts posting items using a BAPI or there is other kind of problem.
Our PI system is connected with other SAP HR systems and always the unicode problems was solved configuring RFC with UNICODE.

Look at the difference if you force collation for the predicate with ">" and/or ORDER BY:
create table test (c1 int, c2 nvarchar(50))
insert into test(c1, c2) values (1,N'पीपे का सबसे चौड़ा भाग')
insert into test(c1, c2) values (2,N'पी')
insert into test(c1, c2) values (3,N'पे')
select * from test order by c2;
3 पे
2 पी
1 पीपे का सबसे चौड़ा भाग
select * from test order by c2 COLLATE Indic_General_100_CI_AS;
c1 c2
2 पी

select * from test where c2 > N'पे' order by c2;

Language Conversion from Unicode 8 to Character Set

Hi,
I am creating a file programmatically containing Vendor Master data (FTP interface).
The vendor name and vendor address is maintained in the local language (Taiwanese) in SAP System, these characters are in Unicode 8 character set.
The Unicode character set should be converted to BIG5 for Taiwanese, and then send this information in the file.
How can I perform this conversion and change the character set of the values I'm retrieving from table (LFA1) to character set BIG5.
Is is possible to does this conversion in SAP, does sap allows this?
/Mike

Hi Manik,
I am also having a similar requirement, as I need to convert the unicode chinese character to GB2312 encoded chinese character,. I already posted in forums but didnt get the required the solution.
Can you please provide the solution which you implemented and also confirm whether it can be used to solve the above problem.
Hoping for your good reply.

Bad Character Errors after Unicode implementation???

Hi,
Uncode is implemented in BW Development system in my project. While prforming unit testing after implementing the unicode, we faced an issue of bad character in Sort field while loading data for 0VENDOR master data. Till now we used to correct this kind of error in PSA level and reload the data from PSA to Data target in production. I hope, this kind of error should be resolved after implementation of Unicode Conversion project. But, even after implementation of Unicode, we faced this problem.
Can you please confirm me my understanding is correct - after implementation of Unicode, bad character errors will disappear?
Best Regards,
Venkata.

HI again,
I would like to correct my statement above. I did encounter an error during the import phase (ie. import abap) where it stopped at SAPDFACT.
I changed the "err" to "ok" in the tsk file to continue cuz I couldnt find any other alternative working. On browsing other forums I have come to conclude that is the problem for sure.
Can you please help me figure how to resolve the issue please .. ??
thank you!

Additional CR when printing unicode character

Hello,
the following code prints two lines on a printer. The second line contains an escaped unicode character. When running the example code I can't even see the unicode character on the paper; but in my original application it is visible. So this is not the problem. But always an additional carriage return is inserted after the unicode character, thus overprinting the beginning of the line with the remaining text. This did not occur in java 6 if I remember correctly. Is there any workaround for this?

Hello Sabre,
thank you for testing. Of course it's good news that you don't see any overprinting, but unfortunately that doesn't help me on my site (Win7 64-Bit, java 1.7.0_09).
Since I can see the character in my original application as I wrote, I made up the following test case and met a strange behaviour. I can make my desired unicode character appear without any overprinting as long as I don't use any other character in the string below 2000(16).
Kindly run the following code. It prints a line of unicode characters starting with my desired one.
Then change iConstant in makeTextLine() to any value below 0x2000. At my site this results in overprinting.
Does it also happen at yours?

Which version of Weblogic on Solaris is compatible with Oracle 8.1.7 - Unicode?

Hi folks,
We want upgrade WLS 4.5.1 to one of the last version of WLS, but also we are
planing upgrade Oracle to 8.1.7 version and migrate the character set of the
database to UTF8 (Unicode),
so we need to know which versions of WLS are compatible with Oracle 8.1.7
and Unicode as Character Set.
Thanks in advance.
Moises Moreno.

Hi Moises Moreno
The latest version of weblogic server is 6.1 with service pack 1. This version
supports oracle 8.1.7 on major unix platforms viz., solaris(2.6,2.7,2.8),
hp-unix(11.0,11.0i), linux7.1, Aix4.3.3 and on windows platforms viz.,
NTwithsp5, 2000.
BEA jdrivers are having Multibyte character set support (UTF8).
Note : Weblogic server 5.1 with SP10 also supports oracle 8.1.7.

Running app doesn't display unicode chars

So far, i didn't care about character encodings. When i setup a string in java i just used my special characters, like e.g. the german umlauts:
String text = "�usserlich �berhaupt nicht sch�n."; //html: Äusserlich überhaupt nicht schön Then i changed the file encoding in my IDE (eclipse) to UTF-8. The first time i reloaded my source files, i had to replace my texts by retyping my special charaters in the source. I thought that would have been enough.
But now, such text doesn't display anymore in a Swing component like a JTextField - instead the special characters are replaced by weird (sometimes multiple) other characters.
The only workaround i've found so far is, to replace all special characters in my source code with the corresp�onding unicode code character "\uxxxx" (backslash + u + 4 chars). But then this would be a step back writing text in the source code. I thought it would be easier to use Unicode ...?
