UTF8 collation for Maltese characters is broken

A full-text search for 'zejt' or 'żejt' brings up the result 'Ħobż biż-żejt', but a full-text search for 'hobz' does not - while one for 'ħobz' does.

I have taken a look at the collation document here: http://myoffice.izhnet.ru/bar/~bar/charts/utf8_general_ci.html

Bizarrely, z==ż, but Ħ!=h. In Maltese h and ħ (lowercase Ħ) are two different characters. But then again so are z and ż. Who draws up the collation algorithms, and are they hard-coded into MySQL?

I am running the latest 5.0 release, and the search is being performed on a MyISAM table with utf8_general_ci collation.

SHOW VARIABLES LIKE 'char%' gives everything except filesystem as utf8, and SHOW VARIABLES LIKE '%coll%' gives everything as utf8_general_ci.
