Treat UTF-8 encoded unicode BOM marked file as an ASCII file (not binary)
Treat UTF-8 encoded unicode BOM marked file as an ASCII file (not binary)

In the interest of maximum compatability, treat BOM marked files as
ASCII.  There is some inherent danger in this because 8-bit extended-
ASCII characters (if present) can play havoc with the Gscope
compression/search system.  For now we're going to err on the side of
being "more open".
