Consider yourself flamed. :)

Only the development version of Lynx (which is installed at exactly one
host in Croatia). Chartrans stuff is still not in the official version.
And my servers are getting too much hits from the old versions of the
other two.

It's not so simple. Stripping extras will work for most of the characters,
but some have two letter ASCII approximations. As far as I know, nobody
assembled tables with ASCII approximations for all ISO 8859-x code pages.
