What is ANSI format?

Question

What is ANSI encoding format? Is it a system default format? In what way does it differ from ASCII?

Answer 1

I remember when "ANSI" text referred to the pseudo VT-100 escape codes usable in DOS through the ANSI.SYS driver to alter the flow of streaming text.... Probably not what you are referring to but if it is see http://en.wikipedia.org/wiki/ANSI_escape_code
