UTF-8 support

Hello All,

Is it possible to make UTF-8 support in PmWiki?

I can change "charset=iso-8859-1" to "charset=UTF-8", but the
following separators create problems when using russian language:

$Newline = "\262";
$KeepToken = "\263";
$LinkToken = "\264";

The third language of russian alphabet in UTF-8 conflicts with one of
them. Can these separators be longer than 1 letter, and can they be
replaced with UTF-8 friendly ones?

The bytes 0xFE and 0xFF are never used in the UTF-8 encoding.
