Which application require this? Could you use UTF-8 or GB2312 instead?
No. I'm a user so please don't ask me to use which codepage. You should ask developer. As far as I know, there is no way to use UTF-8 or GB2312 in some applications.
GB18030 is a Chinese national compulsory standard so many applications use it and then require this codepage. For example: GB18030 converter GB18030 word processor Non-unicode ANSI programs processing or displaying unicode characters Old games displaying unicode characters etc.
What we have to do is to make them binary compatible. That's indeed the goal of Wine project.
Here is a small program modified from ReactOS and in daily use by our team to test: http://dp.r2.lindasc.com/r2/GB18030notepad-6.1.7z But someone complains it cannot run normally on macOS through wine.
