How are charsets handled?
DokuWiki uses UTF-8 (a Unicode representation). This encoding is sent in the documents
meta headers and used as
accept-encoding in the edit form. DokuWiki itself does no reencoding of data sent by the browser, so if the browser ignores the
accept-encoding of the form there may be problems - however all known modern browsers do work just fine with UTF8.
Also see the romanization configuration option.
