Tech Stuff - ASCII Table

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

This apparently simple subject (a character code) turns out to be brutally complicated - well leastways to our modest brains. In the interests of sanity (ours) we have also produced a mercifully short character code overview.

ASCII is a 7-bit code (but encoded in an 8 bit octet) 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 it is not in this table it is not ASCII - there are many other extended character coding systems. MS Word, for example, typically uses CP1252 (latin - 1) among others. This page describes UCS (ISO 10646), UTF-7, 8, 16, Unicode, ISO 8859-anything and other character related stuff which you may find useful. Then again, you may not.
