This support enables users to view virtually any kind of email encoded in various character sets from any region of the world in a single instance of DtMail. DtMail decodes received email by looking at the MIME charset and content transfer encoding provided with the email. Windows-125x MIME charsets are supported.

For sending email, you need to specify a MIME charset that is understood by the recipient mail user agent (mail client), or you can use the default MIME charset provided by the en_US.UTF-8 locale. You can switch the character set of outgoing email, in the New Message window, press Control Y, or click the Format menu button and then click the Change Char Set button. The next available character set name displays in the bottom left corner at the top of the Send button.

If your email message header or message body contains characters that cannot be represented by the MIME charset specified, the system automatically switches the charset to UTF-8 which can represent any character.

If your message contains characters from the 7-bit US-ASCII character set only, the default MIME charset of your email is US-ASCII. Any mail user agent can interpret such email messages without loss of characters or information.

If your message contains characters from a mixture of scripts, the default MIME charset is UTF-8. Any 8-bit characters of UTF-8 are encoded with Quoted-Printable encoding. For more details on MIME, registered MIME charsets, and Quoted-Printable encoding, refer to RFCs 2045, 2046, 2047, 2048, 2049, 2279, 2152, 2237, 1922, 1557, 1555, and 1489.
