I don't know what 'tactis' is, but 'mbcs' is not a portable character set name.
It's a special character set name on win32, which refers to some system-specific
multibyte character set.

I don't think these "failures" are a Python bug.

I suppose, for consistency, it should ideally raise LookupError, though

Maybe so. If that was the poster's point, then I completely missed it.
