If by "file offsets" you mean counting bytes in the file, then those
will also be wrong after decoding non-ASCII characters, unless the
file was encoded in UTF-8 to begin with, right?

And if you mean counting characters in the file, then etags will be
unable to do that, unless it grows the capability to detect the
encoding of the file, or rely on the locale and assume that the file
is encoded in locale's codeset.  Right?

Or am I again missing something?
