Add a String Attachment with a Specified Charset

Demonstrates the Chilkat Email.AddStringAttachment2 method, which adds a text attachment directly from an in-memory string and encodes it using a specified charset. The first argument is the attachment filename placed in the MIME (it is not a path to an existing file), the second is the text content, and the third is the charset used to encode the string. This example attaches a UTF-8 encoded text file.

Background: This is the charset-aware version of AddStringAttachment. Because text must be converted to bytes before it travels in a MIME part, the charset determines how non-ASCII characters (accents, non-Latin scripts) are represented. utf-8 is the safe modern default that can encode any character; the third argument may also begin with bom- or no-bom- to control whether a byte-order mark is written.
