This is the same type of bug (but more difficult) as what I
posted to emacs-devel by the subjest "bad interaction with
C-x RET c and vc-cvs-registered".

A tag file contains file names plus parts of source code.
The former must be decoded by file-name-coding-system, but
the latter must be decoded by the coding system of each
file.  It's very hard to decided a coding system for the
latter without actually reading the file.

Perhaps, a tag file must be read as raw-text (thus in a
unibyte buffer), and if one gives a non-ASCII TAGNAME to
`find-tag', it must be encoded by the
buffer-file-coding-system of the current buffer.
