Text manager and International manager

[Praveen.P.L]

Hi All,

Can any one please tell me following things.
1.How can i write my code for supporting unicode languages.
2.Is there something similar to Unicode support like TCHAR(supported in
windows) in Palm OS, so that it does not always take a single character as 2
bytes(1 Byte for non unicode languages and 2 bytes for unicode
languages).This is because i don't want to use WCHAR(2 bytes) always and
make my application use more memory.

Thanks in advance,
Praveen

I'm not sure what you mean by "unicode languages". Currently Palm OS 
supports several different legacy character encodings, which in turn 
are used by a number of different languages.

If you use the Text Mgr appropriately, your code should work with any 
character encoding, though there is still missing support for 
contextual and bidi writing systems.

Palm OS currently does not support Unicode. When it does, it will use 
the UTF-8 encoding, where every character is represented in a string 
by one to four bytes.

Even today, though, Palm OS supports mixed-width encodings. For 
example, Shift-JIS (for Japanese) is a mix of one and two bytes per 
character in a string. The same is true for Simplified Chinese, 
Traditional Chinese, and Korean.
