    Hi Mark,

    I realize that Stringprep and Nameprep adopted the whole Unicode 3.2
    character set partly because the General Category Values in the Unicode
    Character Database did not appear to be stable yet at the time, and that
    Normalization Form KC was adopted as is, partly because applications may
    already implement that and it would take up more memory to have a
    separate table for Nameprep, but now that we are discussing limiting
    IDNs to Letters, Digits and Hyphen (LDH), which would require a separate
    table anyway, it seems appropriate to question the original inclusion of
    unnecessary characters like double-struck C, and to discuss ways to
    exclude them. No?
