       I think exactly the same way as Markus on all his points. It's
    regrettable but true that all sort of garbages (in addition to
    well-defined useful character encodings) were thrown into it and were
    accepted almost blindly. In other words, there's a serious quality
    control issue.

        Markus may have something different in mind, but I'd add to this
    category coded character set names like ks_c_5601-1987 that are not
    suitable for use as MIME charset.

       Related to the last point is that some charsets are not properly
