Set the Charset of an Email
See more Email Object Examples
Demonstrates the Chilkat Email.Charset property, which represents the main charset of the email, such as utf-8, iso-8859-1, or Shift_JIS. Chilkat stores text internally as Unicode; this property mainly controls how the body text is converted to bytes and labeled when MIME is generated. This example sets the charset to utf-8 and prints the resulting MIME.
Background: Email is transmitted as bytes, but text can contain characters from many languages. A charset (character encoding) is the rule that maps characters to bytes. The email's MIME declares its charset in the
Content-Type header (e.g. text/plain; charset="utf-8") so the receiving client can correctly turn the bytes back into readable text. utf-8 is the modern default because it can represent virtually every character; using the wrong charset is what produces "mojibake" (garbled characters).Chilkat Tcl Downloads
