They are the standard marker to identify a file as UTF-8. This is not  
Mac-specific in any way, it's part of the unicode standard.

You said things did initially work with the UTF-8 marker in place.  
The default code page used by FPC is 8859-1. However, the scanner  
detects the UTF-8 marker if present, and when it finds it then it  
switches the code page to UTF-8. You can also set the code page  
manually to UTF-8 using {$codepage utf-8}.

The UTF-8 marker maybe got mangled somehow by Lazarus or so. I don't  
know why it worked again afterwards when you removed the marker.
