    Hi,
    I have a very basic question. My firefox browser does not show me all unicode characters , but instead little boxes with e.g. "01D4AA" in it when reading e.g.
    "A Survey of Elliptic Cohomology - the derived moduli stack of derived elliptic curves".
    Apparently I need a font which can display these unicode characters.
    Which fonts do I need to have installed to read nLab pages properly? (Or is it that some of the font preferences in my firefox which I have to modify?)
    Thanks,
    Martin

    The short instructions are to download and install the STIX fonts, instructions and download available from this page on the mozilla project.

    The longer instructions are that you need to have enough fonts to cover most of the unicode pages. The STIX fonts are one way to do this, and it means that you get a consistent look, but there are alternatives. There's a little more information at the main instiki web site, in particular this page.

    Should these instructions be made more explicit on the nLab? We talk about what browser to use on the main page, but STIX fonts are only mentioned briefly on the HowTo.

    Yes, we should put that into the HowTo page more explicitly.

    I have the STIX fonts already installed. Nevertheless I have the above problem. Any other ideas?

    To my shame I have to admit that I never much looked into this font issue. Even though it concerns sites that "I am running" myself, with others, I found it a nuisance throughout. These days I feel I am being swamped by all such little things as installing a font here, creating an account there, copying something there, uploading this here, and so on.

    I am running Firefox on Windows with nothing else installed. And it seems that all fonts display correctly. I am aware that this information likely won't help you, though.

    I don't understand how installing the STIX fonts is supposed to help when the CSS doesn't mention them and chooses other fonts instead. Although it does seem to work for some people.

    Let's suppose that you're running Firefox (or SeaMonkey). Then one thing that you can do, which is a bit drastic but should be fine if this is the only site that you read MathML on (and is probably OK even otherwise) is to tell Firefox to use the STIX fonts for MathML in all cases (unless overridden). Then the CSS from Instiki might still make you use different fonts sometimes, but not if a character doesn't exist in that font.

    Put about:config in your browser's address bar, find font.mathfont-family and make sure that it looks like the example here. (Or you can put DejaVu Serif in front of STIXNonUnicode if, as I do, you like that font family better.) Probably you should keep a record of what used to be there in case changing this breaks any other sites.

    Actually, reading that page again, it looks like maybe you should only install the STIX fonts after fixing the configuration? (Although that really shouldn't matter.) So if you did change anything there and it still doesn't work, then try installing them again. Otherwise, I don't know.
