TPTQ Arabic fonts support 85 languages, however not every version of every font supports every language. For example if you use both English and Czech in a document, you need to use a version of the font which supports those two languages.
We offer two different kinds of Arabic fonts: Fedra AR (Arabic), which supports only the Arabic and Mac Roman sets; and Fedra Multiscript, which offers the same Arabic support plus full Latin (Western, Turkish, Central, Eastern European), Greek and Cyrillic.
