Get a Related Item as Text

Demonstrates the Chilkat Email.GetRelatedString method, which returns the text of a related item (with CR line-endings), interpreting the item's bytes using the supplied charset. It is intended for text-based related items such as style sheets. The first argument is the zero-based related-item index and the second is the charset. This example reads an embedded CSS style sheet as text.

Background: Not every related item is a binary image — some are text, like a CSS style sheet embedded so the HTML renders consistently offline. For those, GetRelatedString decodes the bytes back to characters using the charset you specify (typically utf-8). For binary related items such as images, read the raw data via the BinData-based accessor instead. This variant normalizes line endings to bare CR; use GetRelatedStringCrLf when you need CRLF.
