Detect chars such as 007f,...

I want to read a file and process its content in a C99 program. The file have special chars such as 007f and some of them is controller chars.
This is a part of the file:
[code]%'%'''SFUTLNTVERSFUTLNTMODEWelcome to Microsoft

my name is aledra ral

I have 20 boook  you
How can i detect chars such as (that is 007f)?
When i compare each char with 007f in IF_THEN block, i could not detect them.


  • I find solution. I should compare each char with decimal number that peer to unicode. For example 0008 should be compare with 8 for detecting it or 007f should be compare with 127.
