INSTALLING MATH FONTS To install a math font one should add it to the system fonts or install it in the TeX Live directory structure (or both). 1. INSTALLING SYSTEM FONTS a. WINDOWS Window 7 (or newer): Right click on the font file, choose install option. Windows 98 (or newer): Go to Start, then Control Panel. Double click on Fonts, and drag-and-drop the font file into the Fonts applet window. In MS Windows up to XP, in the Fonts applet, you can also choose File from the menu bar, then Install New Font. b. APPLE (MAC OS X) The font can be installed by double-clicking on the font file and following the on screen prompts in the Font Book application, or by manually copying (or dragging) the font file to any of the standard Fonts folders in Mac OS: ~/Library/Fonts/ (user fonts), /Library/Fonts/ (local fonts) or /System/Library/Fonts/ (system fonts). c. LINUX (most of current distributions) Just copy font file to a directory read by font-config. In most cases the directory /usr/local/share/fonts will be adequate (you can also copy the font file to ~/.fonts or /usr/share/fonts ). If the font doesn't appear in the applications font list you can run the fc-cache program in order to force a cache rebuild. 2. INSTALLING FONTS IN TEX LIVE To install fonts in the TeX Live system you have to copy it to the appropriate directory: (TEXMF root)/texmf-local/fonts/opentype/public/ (you may have to create this directory). When you want install fonts for only one user, you can use the ~/texmf/fonts/opentype directory (this directory also may be nonexistent). After coping the font file, you have to run mktexlsr command to refresh the kpathsea caches. Most of the typesetting engines can use fonts installed either in OS or in TeX Live. Microsoft Office (Word) uses, of course, only system fonts. XeLaTeX can use both of them. LuaLaTeX and ConTeXt uses TeX Live fonts by default, but if the OSFONTDIR environment variable is set, the system fonts also can be found. For typesetting math using an OpenType font with (Lua|Xe)LaTeX, an up to date version of the unicode-math package (and related LaTeX3 packages) is crucial. 3. CHECKING THE INSTALLATION In order to verify whether the font installation was successful, you may wish to run the TeX examples or open the relevant MS Word example and compare the results (in case of the Word file, just a previewer is sufficient) with the respective PDF files. Note that, unlike for TeX, an OTF font is to be referred rather by its internalname(s) than by its file name.
