IANA_SUPPORTED folds in IANA_NO_ALIASES, but _IANA_NAMES is built only
from encodings.aliases. Those names are in IANA_NO_ALIASES precisely
because they have no alias entry, so seven of the nine never reach
_IANA_NAMES: cp720, cp737, cp856, cp875, cp1006, koi8_t, koi8_u.
(cp874 and koi8_r resolve only because they also appear in
aliases.values().)

iana_name() therefore raises for an encoding the package lists as
supported, any_specified_encoding() ignores a declared charset of one of
them, and CharsetMatch.output() raises when the target is one of them.
