8     This file is used to enable the iso-8859-2 character set in PmWiki.
9     The first part converts the charset to iso-8859-2 and removes
10     conflicts for newline and keep tokens; the second part
11     handles the conversion of pagenames from utf-8 (sent by browsers)
12     into iso-8859-2 if needed.
