Required Entries

Equation Composer/Document Composer requires access to three special fonts to function properly: a main font, a symbol font and an "extra" font. The main font must contain the ISO Latin 1 alphabetic characters, and is the default font for Latin 1 variables and numbers when no explicit style is given in the MathML markup for an expression. Currently, Equation Composer/Document Composer requires Times New Roman to be available as a default choice of main font, and thus Times New Roman must always be listed in any font configuration file.

The symbol font should be a font with the Adobe symbol encoding, and glyphs for most characters in the encoding. There are two main choices, the standard Adobe Symbol font and the Euclid Symbol font that is installed with MathFlow. Either can be used, but one must be listed in font configuration files. If both are listed, Equation Composer/Document Composer will designate the first one encountered in the listed fonts as the symbol font, and treat the other one as an optional entry.

The 'extra' font is used for pieces of brackets, braces, parentheses, and so on, that are assembled from pieces when required in large sizes. Because the notion of an "extra" font is particular to Design Science products, there are again only two choices, MT Extra and Euclid Extra. Either font is acceptable, but one must be listed in all font configuration files. As with the symbol font, if both fonts are listed, the first one encountered will be designated as the 'extra' font, and the other will be treated as an optional entry.
