how to tell whether external file is unicode formatted or not

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
