First of all I intend to know what is the difference between ANSI encoding and UTF-8 encoding. Say for ex, if I do have a file, how can I test whether that is a ANSI file or a UTF-8 file or how do I prove that a given file is a UTF-8 file.
Also, can I determine the hex values of a given UTF-8 file and compare them with unicode values.
I intend to know more about ANSI,ASCII,unicode,utf-8 etc. Any basic tutorial, plz give the link.
