Font sets
To deal with the problem that a single font may not be enough to display all the characters in a document, or even a single element, CSS1 allows the use of font sets.
A font set in CSS1 is a list of fonts, all of the same style and size, that are tried in sequence to see if they contain a glyph for a certain character. An element that contains English text mixed with mathematical symbols may need a font set of two fonts, one containing letters and digits, the other containing mathematical symbols. See section 5.2 for a detailed description of the selection mechanism for font sets.
Here is an example of a font set suitable for a text that is expected to contain text with Latin characters, Japanese characters, and mathematical symbols:
BODY { font-family: Baskerville, Mincho, Symbol, serif }
The characters available in the Baskerville font (a font with only Latin characters) will be taken from that font, Japanese will be taken from Mincho, and the mathematical symbols will come from Symbol. Any other characters will (hopefully) come from the generic font family 'serif'. The 'serif' font family will also be used if one or more of the other fonts is unavailable.
