    This sounds like an application for SCSU! The Romanian performance will
    take a slight hit from the distinction of comma below and cedilla in the
    Unicode glyph standard, as there will be a 2-byte overhead each to defined
    the windows for Latin Extended-A (a breve and o breve) and the high half of
    Latin Extended-B (s and t with comma below). I expect these characters
    would use 2-bytes, while Latin-1 (a and i with circumflex) would get the
    1-byte codes. ASCII characters would always be encoded as 1-byte in
    alphabetic text.

    What's happened to the old telegraphic standard for Romanian? I understand
    that used 'tz' for t with comma below.
