Is there an existing issue for this?

• I have searched the existing issues

Can the issue be reproduced with the default theme (daylight/midnight)?

• I was able to reproduce the issue with the default theme

Could the issue be due to extensions?

• I've ruled out the possibility that the extension is causing the problem.

Describe the problem

您好我想问现在theme.json中繁体中文的代号是什么？我试过zh_TW和zh_CHT都不生效，繁中还是继续使用简中的主题介绍。

Expected result

希望能支持繁体中文。
