    For example, Mark is referring to cases such as ISO 8859-1 and 8859-15.

    Those share all the same encoded characters except those at
    the code points 0xA4, 0xA6, 0xA8, 0xB4, 0xB8, and 0xBC..0xBE.

    So neither of the repertoires is a proper subset of the other,
    but the two coded character sets share the vast majority
    of their characters, including almost all of the common ones.
