The follow prefixes are define in "interwiki map" with space or non-ASCII-Letter, but doesn't work, see URL:
*[[osi reference model:]]
*[[zzz wiki:]]
*[[Ĉej:]]
The follow prefix is define with underline and works:
*[[doom_wiki:]]
(based on: http://download.wikimedia.org/dewiki/20081011/dewiki-20081011-interwiki.sql and http://de.wikipedia.org/w/api.php?action=query&meta=siteinfo&siprop=interwikimap)
Must the definition in [[meta:interwiki map]] are urlencode? In my opinion it is better, wenn the script can do this or MediaWiki can work without needing of urlencode in interwiki-table.
