32.0. "<special_char>(close_double_bracket)??" by MTWAIN::STOLBERG () Wed Nov 16 1988 08:29

    The online output for the <special_char>(close_double_bracket) tag
    appears to be erratic, especially when used within a routine template.
    The output varies and most often does not appear as expected.  Is
    this a known bug?

    The problem is that the double bracket characters are constructed by
    the text formatter from 2 separate characters (the single bracket
    characters). They are kerned by half the width of a single bracket to
    bring them close together. Output is fine on 300 dot-per-inch printers.
    However, on the video screen, which is only 75 dots per inch, some
    rounding off must be done to align the characters on pixel boundaries.
    So, sometimes the 2 characters are too close together and sometimes
    not: it's very difficult to fine tune at such low resolution. I have
    experimented with the kerning and have gotten better results, but there
    will still probably be some erratic output especially at different
    point sizes. I could take out the kerning altogether, which will
    produce consistent output although you will probably think the
    characters then are too far apart.
    
    If you use double brackets a lot and this is causing huge problems
    for your document, send me mail and we can experiment some more.
