ASCII is defined on character values 0-127. I think you must mean text file,
in which case, you could search a reasonably long prefix of the file (say,
the first 4-16 KB) for the char value zero, which should not appear in any
text file based on a single byte character set such as ASCII or the Windows
"ANSI".
