For example, it is entirely possible that a .pdf file can consist of nothing but ascii text characters however that doesn't mean that trying to print it out with NotePad will look very pretty. The use of the -T operator should not be relied on if the file's extention tells you something else.

RE: How can I figure out whether it is binary file or ASCII file under one directory?
Why not use the -B operator to test the file for
binary contents?
if( -B $file) {
# file is binary
} else {
# file is not binary
}
