Pascal (Lazarus/Delphi)

Get the Decoded MIME Body Text

Demonstrates the Chilkat Mime.GetBodyDecoded method, which returns the decoded body as text. It takes no arguments. Chilkat first reverses the Content-Transfer-Encoding and then interprets the bytes according to the declared charset.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: This gives you the actual, human-readable content of a text part — the two-step decode (transfer encoding, then charset) is exactly what a mail client does to display it. Use it for text parts; for binary content such as an image, decode to bytes with GetBodyBd instead, since forcing binary through a text decode would corrupt it.
