The short answer is that we can post in any language that is supported by Facebook, Twitter and LinkedIn.

The long answer is we store our content in UTF-8.

UTF-8 supports any unicode character, which pragmatically means any natural language (Coptic, Sinhala, Phonecian, Cherokee etc), as well as many non-spoken languages (Music notation, mathematical symbols, APL).

The stated objective of the Unicode consortium is to encompass all communications. The few exceptions which are not supported well (like Klingon) usually have a roman-alphabet equivalent and/or have an unofficial private unicode code page.

If you're concerned about a particular language, see http://www.unicode.org/charts/index.html which shows all the major code blocks (character sets) supported by unicode.

Our interface is in English only.
