437 and 850 *are* codepages. You mean "all those language driver IDs
mapping to codepages 437 and 850". A codepage merely gives an
encoding. An LDID is like a locale; it includes other things besides
the encoding. That's why many Western European languages map to the
same codepage, first 437 then later 850 then 1252 when Windows came

The error idea is fine, but I don't get the "implement it yourself for
practice" bit ... practice what? You plan a long and fruitful career
inplementing codecs for YAGNI codepages?

You're welcome.

?? As far as I can tell, the topic has been about mapping from
something like a locale to the name of an encoding, i.e. all about the
pre-Unicode mishmash and nothing to do with dealing with unicode ...

BTW, what are you planning to do with an LDID of 0x00?
