  Hum, no. That list is just a set for which I have defined integer
values, it's relatively old, and predate the iconv() support.

  The enum should evolve, or get deprecated. The problem is that
there is a set of entry point using the enum to indicate a given encoding
and it's far too restrictive. IMHO all of those should be spotted,
flagged as deprecated and alternative function based on a string should
be used. That part would need a bit of refactoring (while still preserving
the API/ABI :-\ ).
