Can mod_proxy_html support (charset XYZ) as output?
libxml2 uses utf-8 internally for everything. Generating output with another charset is therefore an additional overhead, and the decision was taken to exclude any such capability from mod_proxy_html. There is an easy workaround: you can transcode the output using another filter, such as mod_charset_lite. mod_proxy_html 3 supports output transformation to other charsets using ProxyHTMLCharsetOut. This requires mod_xml2enc to be loaded.
