I am working on a pattern matching routine for a header signature. To avoid running through many possible matches, I will like to start the looked-for pattern with an ASCII character that is rarely used on any kind of text file. The only restriction is that the character must be a printable one (no control chars allowed). Thus my question is: 1. Which alphabetic letter is the least frequently used (among lower and upper case on text files)? 2. Which special character ('@#$%^...etc) is the least frequently used on electronic mail files?
