The "Language Encoding" setting in the Publishing Options area now also effects the encoding of the Subject Line and the From Name of outgoing email messages. It is now possible to choose any of the available encoding formats and enter text in any of these supported languages.
Additionally, there is a new setting under Publishing Options called "Character Encoding" that determines what method of character encoding will be used when structuring the Subject and From Name. For most situations, the "Base 64" option should be used, but another option, "Quoted Printable" is offered for greater flexibility. There is also a "None" option if you do not wish the Subject or From Name to be encoded at all.
The combination of Language Encoding and Character Encoding that you should use will depend upon the nature of your audience and the types of email systems most frequently used within the region that they live.
