Improve error message and ctests for input encoding cp858.

Encoding cp858 supported by only some iconv variants.
Most users will want to change their "encoding" setting instead
of installing/recompiling "iconv" to support this legacy encoding.

ctests are likely will fail with either "vanilla" or "enhanced"
iconv and test a situation that is unlikely to change generally,
so we ignore this test now by default.
