Pascal (Lazarus/Delphi)

Set a MIME Body from Plain Text

Demonstrates the Chilkat Mime.SetBodyFromPlainText method, which sets the body as plain text. The only argument is the text. For ASCII input Chilkat uses text/plain with 7bit encoding; for non-ASCII it selects an appropriate charset and encoding.

Background: This is the simplest way to give a MIME entity a text body — Chilkat picks a sensible Content-Type and transfer encoding for you based on the content. Plain ASCII stays as 7bit with no charset, while text containing accented or non-Latin characters gets a charset (typically UTF-8) and a suitable encoding so it survives transmission intact. It is the text counterpart to SetBodyFromHtml and SetBodyFromXml.
