ISO-8859-15 and 16! I don't know anything beyond ISO-8859-10. Can you
give me any pointer (URL) explaining what they are?

Probably this is because Unicode is not perfect at all. For example,
the concept "encode everything in two-bytes" is obviously broken

etc. etc...

Docs for MULE internal code come with XEmacs. For example, see:

ftp://ftp.xemacs.org/pub/xemacs/docs/letter/internals-letter.pdf.gz

http://www.lns.cornell.edu/public/COMP/info/xemacs/internals/internals_15.html#SEC83

etc.
