Perhaps the flag discussed below should have another default value
on the relevant architectures.
(Nobody reported the problem since 1998 before you)...

The encoding of newly created bookmark in that case will be us-ascii.

Just imagine: you read cyrillic texts and european texts (latin with
ascents), and the first bookmarked document is in iso-latin-1.
In this case all subsequent cyrillic links will be transliterated,
which is not nice. You suggest a new kind of "randomness", dependence
on the charset of the first bookmarked document.

Yes, it would be better to use bookmark in utf-8,
but only when utf-8 editors will be widely available.
