    U+0000 up to U+007F take 1 byte (ASCII)
    U+0080 up to U+07FF take 2 bytes (Latin-1, Latin extended,
    combining diacritics, phonetics, greek, cyrillic, hebrew,
    arabic, syriac, and some more scripts - this is very little
    expansion especialy for laguages which use only few non-ASCII
    characters like swedish or german but expensive for greek or
    arabic or so)
    U+0800 up to U+FFFD take 3 bytes (hangul, cjk... not to
    expensive but significant)
    U+10000 up to U+10FFFD take 4 bytes (this is all the rest -
    take almoust everywhere 4 bytes, so this is no significant

    If space is a concern, use SCSU - this shorter and has the
    additional advantage of beeing very much better compressable
    by zip or comparable algorithms.
