Charset::Baudot - allows to use Baudot string constants in ASCII programs (and v.v.)


    use Charset::Baudot;

    my $a = baudot2ascii"(Baudot text)";


Charset::Baudot defines functions to convert between a subset of ASCII and a subset of nonstandard Baudot - the original Baudot allows only letters, numbers, and some punctuation. We assume that a Shift to letters code while already in letters mode means Shift to lowercase and Shift to figures while already in figures mode means Shift to symbols. This allows to use up to 120 characters. However, for simplicity some characters are available in multiple sets, so the total is less than that.

By default, both functions baudot2ascii and ascii2baudot are imported in your namespace. If you don't want that, you know how to avoid it. They do the obvious thing to their first argument and return the transformed string.

There is another function, standardbaudot, not exported by default, which sets the module's behaviour to shandard Baudot.

Well, that's all.


The following are the characters recognised. As described, the shift characters have nonstandard meaning.

This module reimplements some of the functionality of two other modules (see Exporter, Carp, Reinventing the Wheel). This is intentional, as it will leave larger scope for obfuscation in a future release.
