Re: IBM AIX 5 and GB18030

[Markus Scherer]

Jane, you are right, I over-simplified. I tried to make the point that you need not _process_ text in GB18030 but that Unicode processing and conversion to/from GB18030 fulfills the requirement to be able to read and write GB18030 text.

Yes, you need to have font support for all the characters that China tests, and there might be IME requirements, too. I am not familiar with the actual certification tests. However, as far as I understand, China tests visible behavior, not implementation details. If you can read/write/input/output/display the required set of GB18030 characters, then you pass. For more details please contact your Chinese subsidiary or the Chinese authorities.

I think only "converter" is not sufficient. How about the following
support :
- IME (to input CJK Ext.A characters through GB18030/Unicode code)

possible

- X-Windows fonts support.

Some font support, not necessarily X-Window fonts - however you manage to display the required characters.

- iconv support
- mbtowc(), mbstowcs()

These are all flavors of converter APIs.

, mblen()...
- and so on...

These are processing functions. If you process Unicode internally, then you use Unicode equivalents of them.

You need be able to do like what you can do on Solaris and HP "setenv
LANG zh_CN.GB18030" to enable those support.

zh_CN.UTF-8 should suffice, as explained.

The conveter mentioned on the Web site you fond to me is just a
utility.

My understanding is that that converter would update iconv. I do not know the details of this AIX fix however.
