Brion-
Another possibility is simply to 'blacklist'
known problem browsers by
printing a notice/link to better browsers on the edit page warning that
they may have problems,
For the record, I would support blocking problematic browsers from editing
entirely. If UTF-8 has enough advantages (and many people seem to think it
does), then telling 2% of the userbase that their browser is outdated and
corrupts pages when editing seems acceptable. Perhaps we can do it in a
smart way and provide links to alternatives for each blacklisted browser
(e.g. Netscape 4->Mozilla).
On the other hand, I would not support any solution that still leads to
corrupted pages.
