Get an Attachment as a Text String

Demonstrates the Chilkat Email.GetAttachmentString method, which returns the Nth attachment's data as text. The first argument is the zero-based attachment index and the second is the charset used to interpret the attachment bytes. This example reads a text attachment as utf-8.

Background: Attachments are stored as bytes, so turning one back into a string requires knowing its charset — the rule for mapping bytes to characters. Supplying the correct charset (often utf-8) yields readable text; the wrong one produces garbled characters. This method is meant for text attachments such as .txt, .csv, or .xml; binary attachments should be handled as raw data instead.
