Set the Charset of an Attachment

Demonstrates the Chilkat Email.SetAttachmentCharset method, which sets the charset parameter of the Content-Type header field for the attachment at a given zero-based index. This example adds a text attachment and sets its charset to utf-8.

Background: For a text attachment, the charset parameter tells the receiving client which character encoding the bytes use, so accented or non-Latin text renders correctly. Setting it explicitly (typically utf-8) removes ambiguity when the attachment contains non-ASCII content — without it, a client may guess wrong and display garbled characters.
