This part I do not understand, Mojca; surely the patterns /define/ the
size of the alphabet, do they not ?  If letter <xqqyn> is not in the
patterns, then TeX cannot hyphenate a word containing letter <xqqyn>,
can it ?

It was, in part, the existence or otherwise of such a tool that
interested me, as well as whether XeTeX could natively handle such
patterns were they to be generatable ...  A /very/ quick look at
Patgen.web suggests (to me) that a re-implementation in Perl might be
the fastest way forward (Patgen is run so infrequently that the run-time
overheads of an interpreted language are irrelevant) but I regret I have
too much on my plate at the moment to volunteer to investigate further.

That is indeed seriously ugly.  The sooner the whole of the TeX suite
has native UTF-8 clones, the more chance there is of TeX surviving into
the 22nd century, it seems to me.
