Ken - I of course understand and share your concerns. But there
are people who have attempted to do it. One case I know is the
mule (multilingual emacs) project at ETL in Japan. They have done
both Arabic and Devanagari. It doesn't work at all if the fuction
is for single characters, but it produces results for a string
of charcaters. A case again where the function interface can make
a big difference.
