Hi Newlib team,


I have partially able to do for shift_jis by creating tables using
1. wget ftp://sourceware.org/pub/newlib/newlib-4.2.0.20211231.tar.gz
2. tar -xvf newlib-4.2.0.20211231.tar.gz
3. cd newlib/libc/iconv/ccs/

4. wget https://www.unicode.org/Public/MAPPINGS/OBSOLETE/EASTASIA/JIS/SHIFTJIS.TXT
5. ./mktbl.pl  -S SHIFTJIS.TXT
 6. cd ../ces/
 7. ./mkdeps.pl
It seems I need to handle more in the scenario when a string is mixed with English and Japanese


Regards,

Hi newlib team,
In the project I am working there is requirement to covert UCS2 to following code pages

1.       Chinese: gb2312
2.       Japanese: shift_ jis
3.       Russian : cp1251
4.       Hungrian, Polish and Cesky: cp1252
5.       Default:cp1250
I could see that items 3-5 are supported in newlib iconv library.

For gb2312  or gbk  I could see that it's supported in Cygwin-windows only. Is there a feasibility issue to support gb2312 for embedded cortex M controllers?

I can see Jis implementation in newlib and but is not available for Cygwin.Is It available for embedded   cortex M controllers?

What is the difference between jis and shit-jis

Thank & Regards,
Anas N
