Unicode Subscript issue (Khmer Script)

[subin83]

Hi,

I am having an issue with Khmer Unicode font. The program reads from a UTF-8 file and then writes the string to a JPEG file. In Khmer font there are subscripts for each character. These subscripts are appearing as a separate character in the JPG file. Please see "not_needed.png"(

in the attachment. The needed.png(

shows the correct display as shown in the text editor. I am able to get the correct format by using Javascript also. But not with Java.
Do someone have any idea as to why Java separates the subscript unicode character? I use Kh-Battambang.ttf as the font for displaying. As far as I know in Indic fonts also subscript is there.

I would be very thankful if someone could give me pointers to where the issue is. Thanks in advance.

Regards,
Subin

Maybe it's just me but I don't get the problem. Are you using Java for generating the jpegs from a text file? If so, can you show us some code?

Cheers,

Hi Dian,

Thanks a lot for the mail. Yes I am using Java to generate JPEG's from text file. Please see the abstract of the code below.

Also I tried an online applet (

http://www.easybabel.com/html/kh-khm-kbd.html)

which basically is an online Khmer keyboard. There it is possible to open an UTF-8 document and also paste the khmer text. I tried it and there also i am getting the same issue. I read that from Java v 1.6 khmer is supported and I run v 1.6.
Also if you see in this conversion site (

http://rishida.net/tools/conversion/)

for decimal NCR (ថៃ្ងសម្រា&#6016 we get the corresponding text as ?????????? If I copy this text and paste to the online applet described above, I still get the issue where the subscript is removed from the parent.
Does this have to with my font settings in the java lib directory? or is this incompatibility of the font?
