What has the locale to do with that? The set of encodings to encode a
particular Unicode character is independent of the locale...

Yes, that's a good approach. However, I'd recommend to use the
locale's encoding instead of the system default encoding, as reported
by nl_langinfo(CODEPAGE).

As for computing the list of possible encodings: I'm not sure what the
best data format for that would be.
