    Hello Andreas Prilop,

    you have written:

    In this case, its a matter of fonts rather than programs.
    Try several fonts, including TITUS Cyberbit Basic
    and some of the SIL fonts
    to see various degrees of standards compliance.

    This is still a good advice for HTML authors. However, the reader
    will sometimes see the precomposed letter from a different font
    than the surrounding text (if the character is not available in the
    current font, some browsers will try a different font for that very

    Id rather say: Use standard-complying e-mail software,
    e. g. Imp <>.

    What sort of surprise do you mean?

    Again, the outcome depends on the font used (tested with IE 6 SP2).
    To mention only a few:
    - Times New Roman, Verdana, and the various Lucidas,
       have rectangles (missing-character glyphs), rather than ties;
    - Palatino Linotype, and Sylfaen, have invisible glyphs,
       rather than ties;
    - Tahoma displays ties, but not properly placed;
    - TITUS Cyberbit Basic displays most of the ties alright,
       only on iz, jz, lz, and mz the ties are not properly placed;
    - Gentium (from SIL) does an even better job than TITUS Cyberbit Basic;
    - all fonts tested have no special glyphs for uppercase base characters.

    Best wishes,
       Otto Stolz
