Thanks for the report. I don't speak Chinese, but adding FULLWIDTH COLON
to the regexp makes sense to me.

Similar problems were reported for Comint (bug#13124) and Eshell
(bug#31075), and both `comint-password-prompt-regexp' and
`eshell-password-prompt-regexp' contain now "[:：៖]". I've changed
`tramp-password-prompt-regexp' accordingly.

I've pushed this to the emacs-29 and master branches. Tramp 2.6.0.1,
which will be released later today on GNU ELPA, contains this patch as
well.

Thinking about, it might be worth to declare a respective defconst (in
the master branch). There exists, for example, "﹕" (SMALL COLON), which
might be added to this list, don't know.

Best regards, Michael.
