    This question of non-Ascii filenames is a real problem : hardly any
    software out there can cope with this.
    I did not know of RAR, but have given it a try. Even here there is a
    serious problem, because if the filename is non-Ascii the name of the
    compressed file comes out as _____.rar, with as many underlines as there
    were characters in the original name. In fact it is a bit less predictable
    : if the name is Greek, for example, you get Latin letters, if it is
    Cyrillic, just the underline.
    This is useless then if you have a number of filenames all with the same
    number of characters.
    Certainly more work is needed on RAR (at least on the Win 2000 version).

    I know about that, since I made my Fontlist 5 work properly with arbitrary
    non-ascii names : .
