Tech Info ASCII Table

Mercifully short character code overview. An apparently simple subject which turns out to be brutally complicated - well to our modest brains.

Good old ASCII Table - we can never find one when we need it. Print it, stick it on YOUR wall and save OUR bandwidth!!

ASCII is a 7-bit code (but encoded in an 8 bit octer) and is the US national implementation (ANSI X3.4-1986) of the IA5 character set defined in ITU-T T.50 - so there you go!

If you are into HTML encodings e.g. ©,™, € etc.. Remember if it is not in this table it is not ASCII - there are many other extended character coding systems. MS Word uses CP1252 (latin - 1) among others.
