Hi,

I'm wondering, how to determine is a file is a text file, or a binary
file, programatically. I'm thinking about reading 4 bytes from the
file and test them if they're in the range of usual text ([a-z],
[A-Z], etc. The 4 bytes is read from the following locations : 1st
byte, last byte, and 2 randomly selected offset inside the file. Is
this enough?

TIA
