Best way to search files for non-printable characters?

I need to check ftp'd incoming files for characters that are not alphanumeric,<tab>, <cr>, or <lf> characters. Each file would have 10-20,000 line with up to 3,000 characters per line. Should I use awk, sed, or grep and what would the command look like to do such a search? Thanks much to anyone...

bbcombotest

BBCOMBOTEST(1)						      General Commands Manual						    BBCOMBOTEST(1)

NAME

       bbcombotest - Xymon combination test tool

SYNOPSIS

       bbcombotest --help
       bbcombotest --version
       bbcombotest [--debug] [--quiet]

DESCRIPTION

       bbcombotest is a Xymon extension script that runs on the BBDISPLAY server.  It combines the results of one or more of the normal Xymon test
       results into a combined test result, using standard arithmetic og logical operators.

       The resulting tests are sent to the Xymon display server as any normal test - so all of the standard Xymon functions  (history,	statistics
       etc.) are available for the combined tests.

       The  tool  was born from the need to monitor systems with built-in redundancy and automatic failover - e.g. load-balanced web servers.  But
       other uses are possible.

OPTIONS

       --quiet
	      Normally, the test status sent by bbcombotest includes information about the underlying test results used to determine  the  current
	      value of the combined test. "--quiet" eliminates this information from the test status page.

       --debug
	      Provide debugging output for use in troubleshooting problems with bbcombotest.

       --no-update
	      Dont send any status messages - instead, the result of the combotests is simply dumped to stdout. Useful for debugging.

FILES

       $BBHOME/etc/bbcombotest.cfg
	      Configuration file for bbcombotest, where the combined tests are defined

       $BBHOME/etc/hobbitlaunch.cfg
	      Configuration file controlling when bbcombotest is run.
