Multilanguage support is not yet fully tested but was implemented.

Either way the rendering was programmed with metacharset set to UTF8.

Please check if your database UTF8 ready (this is not a requirement).

TYPOSCRIPT SETUP

config.metaCharset = utf-8

HINT:

If you get funny characters and do not have permission to set the database configuration to UTF8 you may try to make your inputs to database using HTMLENTITIES instead of special characters.
