Why does such a powerful SublimeText cannot set
“default_encoding”: “GBK”,
What do you mean by “support directly”? ST will always display the actual characters in a file, it’s not a wysiwyg editor. Though you could create a plugin or syntax definition for ansii colors.
“Support directly” means that users can directly edit gbk encoded text without other plug-in extensions.
such as editplus…notepad++…text…
GBK text can be complied directly
without coder33 or convertoutf8.
So you want to edit individual bytes. Sublime is a text editor, not a bytes editor. That said you can use e.g. https://packagecontrol.io/packages/HexViewer
It means I can directly use File->Reopen with encoding->GBK, rather than installing third party plugin.
GB18030 is backwards compatible with GBK and has been supported since build 4123 from 2021.
