Afaik it is. The unit is just the main conversion, and can be plugged with
units that are generated directly from unicode.org tables.

Our own cache of those tables are in ucmaps, and the tool to make units out
of them is utils/creumap.pp. Examples for such units are compiler/cp*

The only problem is that it uses UTF16 internally iirc.

Maybe expanding charset with a utf16<=>utf8 conversion, and making a package
with units with some common encodings would do it also.
