What did you do?

I used a Chinese package name (folder name)
report errors: routers\router.go:46:2: malformed import path "gitee.com/xxx/xxx/controllers/用户管理/消息管理": invalid char '用'

What did you expect to see?

I hope the new version can support Chinese package names. After all, Go1.15.15 has been supported before, and has been used in multiple projects.

What did you see instead?

In versions after go1.15.15, Chinese cannot be used as the package name (folder name)
