How are you encoding the symbol/glyph you send, before/as you send it? Have you checked the receiving device that it has a font that can actually disply that symbol/glyph properly?

If you don't use your own J2ME app, but the built-in Messaging app to send it, does it work then? What's the character/text encoding setting for text messages in/for the built-in Messaging application on the phone? E.g., on the N8, the possible options for character encoding is "Reduced support" or "Full support". I think with "Reduced support", the encoding is the default, 7-bit "SMS alphabet" (might also vary based on the phone's firmware language), but with "Full support" it is Unicode (UCS-2).

You may also need to post relevant pieces of your source code as well as device details (which devices models and on which firmware version things work, and on which it doesn't).

Hello iraqy2010,

can you provide more information on this by answering the questions by petrib please?

How are you encoding the symbol/glyph you send, before/as you send it?

that code in this site

I want to edit it and replace

{'a', 'b', 'c'};

to

{'ُ ', 'ٌ ', 'ِ'};

but not appear
how to me do that
and about questions of petrib ,I dont know how to check the receiving device that it has a font that can actually disply that symbol/glyph properly
how to me do that???
I am new on the programming and i need help u
