But such a solution is not clean, you cannot plug in such logic to the
TeX mouth when the input is being read nor to the output stage when
TECkit maps are in effect. I wrote the reasons earlier. The only
reasonable solution seems to be the one suggested by Phil Taylor, to
extend \catcode up to 255 and assign special categories to other types
of characters. Thus we could say that normal space id 10, nonbreakable
space is 16, thin space is 17 etc. XeTeX will then be able to treat
them properly.
