Mac Forum / Applications / Eudora / April 2007

> This plugin checks all incoming messages (and can be invoked manually)
> for UTF-8 encoding and tries to decode as much as possible. It is
> naturally limited, because Eudora can only handle the characters in the
> ISO8859-1 charsets, so for example Japanese characters can't be decoded.

> To check if a message is UTF-8 encoded, the plugin looks at the message
> header "CONTENT-TYPE:" and checks if it contains the strings "CHARSET"
> and "UTF-8". If those strings are not found, the message stays untouched
> in the automated mode. In manual mode, this check is turned off to give
> you the chance to decide yourself if a conversion is needed. Only
> message parts of the type "text/plain" and optionally "text/html" are
> processed, so binaries stay untouched. Multiline message headers are
> supported.
