Curt,

The default way is to show an open-file dialog, asking the user to choose the file and select an option from a menu with encodings.

You can use unicode signatures to determine the encoding, but UTF8 doesn't need a signature officially and UTF16 files may not have the signature either. Here's some information about unicode BOM signatures <http://unicode.org/faq/utf_bom.html#BOM>.

My app reads in external files that are stored as plain text, but the encoding can vary. Is there a way to tell whether the encoding is Unicode or not, so I can tell how to process the text (without asking the user, who may not know)?

thanks,

Curt
