Multilingual means relating to or supporting more than one language.

Typotheque Webfont Service supports all characters that our fonts support. Look up the particular font that you are interested in, and see all Glyphs that it support. For example, Fedra Sans Book supports over 2500 glyphs.
Typotheque designs and develops Unicode-compliant fonts. Below are some instructions for using Unicode fonts to set Devanagari texts.
Up-to-date information about languages currently supported by our fonts is here.
Typotheque 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.
In order to use Arabic fonts, you need to use special versions of InDesign, PhotoShop or Illustrator. These versions are labeled ME (Middle Eastern) and support bi-directional text setting for Arabic, Farsi and Hebrew. The regular version of Adobe CS3 doesnʼt support Arabic text setting.
Although the notion of serif/sans serif doesnʼt exist in Arabic typography, we created two different packages for Fedra Sans and Serif. Obviously only the Latin characters are serifed or not; the Arabic glyphs were then designed to match the typographic ʻcolourʼ of the text, so the Sans is slightly heavier than the Serif because...
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.
Briefly, OpenType is a font format jointly developed by Adobe and Microsoft in the late 1990ʼs. It came into wider use only after 2000, when Adobe included support for advanced typographic features in their InDesign, PhotoShop, and Illustrator applications.
We offer fonts primarily in OpenType format. OpenType is the only cross-platform format, i.e. the same file will work on both Macintosh and Windows computers.
If you only work with Latin-based languages (e.g. English, French, Polish, Czech or Turkish) then our OpenType Std fonts will meet your needs. If you also require support of Vietnamese, Russian or Greek, then you’ll need OpenType Pro fonts.
Typotheque has more than 15 years of experience in designing custom type. Custom type may include modifications of our retail fonts, creation of different language versions of our fonts (Greek, Cyrillic, Arabic, etc), or entirely new fonts made to fit your needs.
