ASCII "bang bang"
=================

   This charset is available in `recode' under the name `Bang-Bang'.

   This code, in use on Cybers at Universite' de Montre'al mainly,
served to code a lot of French texts.  The original name of this
charset is "ASCII code' Display".  This code is also known as
"Bang-bang".  It is based on a six bits character set in which
capitals, French diacritics and a few others are coded using an `!'
escape followed by a single character, and control characters using a
double `!' escape followed by a single character.

   The routines given here presume that the six bits code is already
expressed in ASCII by the communication channel, with embedded ASCII `!'
escapes.

   Here is a table showing which characters are being used to encode
each ASCII character.
