Does anyone have a sure fire way to determine if a file is binary or

I have need to create an import utility that will import data from a
text file (csv, tab-delimited, etc) into a database, but I'd like to
check the file before doing anything else just to make sure it is in
fact text and not binary.
Just a guess here but how about reading the file twice: once as file:
and once as binfile:
If the two are identical, then I assume it's text only.
I have no idea if this will work, but it's worth a try :-)

The solution won't scale, and it also depends whether it would handle
multi-byte characters (use for Kanji for example) and certain UNICODE
formats that use the NULL character.
If this is on a particular platform, then there are various ways to do
this. On Linux/UNIX systems you can run `file <filename>` in order to
classify a file for example.
