Which languages are supported in Streamio?
 

ANSWER
 

Texts appear in different places in Streamio, in published movies as well as logged in to the Streamio account. There are movie titles, user information, tags and lots of other things. Each language consists of a character encoding. Threw the overriding file format UTF-8, which is supported by Streamio, most of the character encodings are handled automatically, see list:

This list tells which languages are supported by Streamio.

Still, there could be an issue due to the font used to show some characters. If this font doesn't support a certain character encoding those characters will be rendered/shown by a default font which has this support. This fall back is automatized in the web browser and will just cause esthetic differences.

An exception is flash players who could have embedded fonts with no fall back and therefore render wrong characters. 

Computers with no fall back fonts is an other exception. This seems rare in modern Operative systems but in old versions of Windows it could be necessary to install for example a special asian character encoding.
