user-defined external format?

I'm working on some code that interfaces with the Lotus Notes C API. Lotus Notes us something called LMBCS[1] internally, which does not seem to be supported directly by Lispworks. (LMBCS is based on CodePage 850, but with "shift codes" to access characters outside the CP850 set).

Is there a way to extend the set of external formats available in Lispworks?

I believe many of the Russians miss KOI8-R, the most popular encoding
of Russian on *nix.

Edi's flexi-streams supports CP850, KOI8-R, and almost every encoding
one could wish. It is quite universal but is not very efficient IMHO.

Re: user-defined external format?

FLEXI-STREAMS doesn't directly support the Lotus Notes external
format, but it should be fairly easy to add that.

It is indeed true that FLEXI-STREAMS - because it tries to be flexible
and to work across many different Lisps - isn't very efficient
compared to native implementations.  The 1.0.x versions are a lot
faster than older releases, though.

Cheers,
Edi.
