How much this matters depends on your programming
environment. If your program internally uses 'real'
Unicode wide chars, at some early point you translate
all the CESU-8 into wide chars (or vice versa).
Or, by the joys of open source, you change UNICODE_FSS
behaviour or add a better UTF-8. There's only about one
thing to be changed: the conversion to and from
Firebird's internal UTF-16.

Yep. Unfortunately I volunteered (at a moment where
I had more spare time) to give the Firebird INTL architecture
an overhaul. Not much done yet, sorry.
You can find a basic example for a loadable collation
in the firebird-architect file area.
