SimplePie::set_output_encoding() WP 1.0

Set the output encoding

Allows you to override SimplePie's output to match that of your webpage. This is useful for times when your webpages are not being served as UTF-8. This setting will be obeyed by {@see handle_content_type()}, and is similar to {@see set_input_encoding()}.

It should be noted, however, that not all character encodings can support all characters. If your page is being served as ISO-8859-1 and you try to display a Japanese feed, you'll likely see garbled characters. Because of this, it is highly recommended to ensure that your webpages are served as UTF-8.

The number of supported character encodings depends on whether your web host supports mbstring, iconv, or both. See http://simplepie.org/wiki/faq/Supported_Character_Encodings for more information.
