    ... if you had binary files that you wanted search ...

I actually meant ASCII files with one or two corrupt lines containing binary data - more specifically ^Z - the DOS EOF character which perl sees as the perfect opportunity to jump out of a while loop early (unless binmode is in effect).

I'm not sure what you mean by

    Unfortunately, turning binmode on by default would be problematic as well.

but I think I have a solution - use open. The open pragma affects I/O ops for the script and from perldoc open comes the following snippet

    The ":raw" discipline corresponds to "binary mode" and the ":crlf" dis +cipline corresponds to "text mode" on platforms that distinguish betw +een the two modes when opening files (which is many DOS-like platform +s, including Windows). These two disciplines are currently no-ops on +platforms where binmode() is a no-op, but will be supported everywher +e in future.

which may solve whatever problems you are suggesting binmode causes.
