Does mod_accessibility support non-European character sets such as Russian, Chinese or Arabic?
It should, though we don’t have the capability to test it. In order to support this, mod_accessibility needs to know the encoding of the data it is processing. It will read this from the Content-Type header set by Apache. For example, if you use Apache’s AddCharset directive with ISO-2022-JP, then mod_accessibility will read its input as Japanese. Output is always set to utf-8 (unicode), which is widely supported by web browsers and XML processors. If you want more flexibility, you can use mod_accessibility together with a transcoding module such as mod_charset or mod_charset_lite.
