    ";" in many (though not all) mnemonics means "ogonek", so its presence here
    is reasonable, considering that this character (which appears only in
    ISO-IR-158) is the original "High Ogonek". Since ISO-IR-158 is for Saami,
    perhaps "S" stands for "Saami". Writing "S;" would erroneously suggest
    "S with ogonek".

    As RFC 1345 says, you write &THI for the first case, T&HI for the second, and
    THI for the third. Mnemonics that are not two-character are written
    &_..._ in context, thus U+1ECD ("o" with dot below) is written &_o-._
