  • 9 displays as - in every browser

    From Bob Tennent@21:1/5 to All on Fri Apr 2 12:44:07 2021
    On my CentOS-7 system, "9" displays as "-" in google-chrome,
    chromium, firefox, vivaldi, and opera. Why?

    Have you ruled out a corrupt font file?

    Have you ruled out a corrupt font file?
    Seems to happen only for certain web sites.

    And are those web sites specifying a particular font?

    Have you tried this on another device? Maybe it's something about the
    site(s). If it's only certain web sites, you could share and maybe
    someone else running CentOS-7 (I'm not) could try to reproduce.

    Have you tried cut-n-pasting the text to see if it shows up as a - or a
    9 in another program? Consider trying programs that support HTML paste,
    like Libre Office, and those that don't, like ed/vi/emacs in an xterm.

    really, what have you done to try to really identify the problem?

    Yes. Another CentOS-7 system. No problems.
    ...
    Selecting a title with 9s and pasting into an xterm shows
    the 9s.

    All consistent with a corrupt font. Checksum the font files and compare
    with the working system. It might be something else still, but that
    seems most likely now.

    try Web Developer -> Inspector to find the font by name

    Seems to be one of "Lucida Grande","Trebuchet MS","Verdana","Helvetica","Arial",sans-serif;

    fc-match Lucida Grande fails but fc-match Trebuchet reports

    DejaVuSans.ttf: "DejaVu Sans" "Book"

    Is that the suspect font? I opened my DejaVuSans.ttf in
    fontforge and 9 is 9. Same with all the others.

    Is that the suspect font? I opened my DejaVuSans.ttf in
    fontforge and 9 is 9. Same with all the others.

    Using the following test file:


    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD><TITLE>Bookmarks</TITLE>
    <style type="text/css">
    body { font-family: "Lucida Grande";}
    </style>
    </head>
    999
    </BODY></HTML>

    I've determined that my Lucida_Grande.ttf is the problem
    (though in fontforge it is showing 9 as 9). After removing
    Lucida_Grande.ttf from my system (and calling fc-cache) the
    problem has been solved. Thanks!

    I had problems like that when I was overclocking my video card,
    rebooting or restarting X11 would temporarily fix it.

    Firefox inspector (which is the only one I've used recently, and not
    much) underlines the font being used.

    fontforge and 9 is 9. Same with all the others.

    Fontforge must be using the font files differently, but I can't say how.
    Fonts are complicated.[*]

    Using the following test file:
    ...
    <style type="text/css">
    body { font-family: "Lucida Grande";}
    </style>
    </head>
    999
    ...

    I've determined that my Lucida_Grande.ttf is the problem

    That's good. Corrupt fonts are not common, or at least not commonly
    noticed. If ¥ prints as ₩ but you never buy anything in Yen or Won, you might not realize the problem.
