Type: string
Default: "us-ascii:iso-8859-1:utf-8"
A list of character sets for outgoing messages. Mutt will use the first character set into which the text can be converted exactly. If your `` $charset'' is not iso-8859-1 and recipients may not understand UTF-8, it is advisable to include in the list an appropriate widely used standard character set (such as iso-8859-2, koi8-r or iso-2022-jp) either instead of or after "iso-8859-1".
