Hm. I was so concentrated on looking for a luatex solution that I
didn't consider the standard tools. I will check ttf2tfm and otf2tfm
but I fear they will generate only tfm's with the standard maximum
of 256 character.

I know that normal tfm's should contain only 256 chars. But after
all a tfm is more or less only a long list of 
 (CHARACTER <number>
  (CHARWD ...)).

So I don't see a logical reason why one shouldn't be able to
generate a large tfm with the informations of more characters (and
luatex is generating large "virtual tfm" with metrics information).

I want to try out if tex4ht can handle such large, unstandard tfm's
or if it has built-in a hard 256 barrier.
