True Type Collections (TTC) You can use True Type Collections (TTC). TTC support is necessary for certain Japanese and non-Western typefaces. All information and instructions regarding TTF fonts in this document also apply to True Type Collections. If the True Type Collection has an English name and a locale specific name (for example a Japanese name), you must update the driver file with separate entries for both of these names. For some languages, you must run the language version of Windows to be able to see the locale specific names.
