typical regex problem

This is a bit of a FAQ, worth searching for.

My slant is to advise using regular expressions
Research regexes (regular expressions) for the environment you are using.
In most environments (perl, bash, C) you will find the character classifiers 'isalpha', 'isdigit' etc very helpful.

NAME
Charset::Baudot - allows to use Baudot string constants in ASCII programs (and v.v.) SYNOPSIS
use Charset::Baudot 'baudot2ascii'; my $a = baudot2ascii"(Baudot text)"; DESCRIPTION
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 sim- plicity some characters are available in multiple sets, so the total is less than that. Two functions, baudot2ascii and ascii2baudot, are exportable (but not exported by default). They do the obvious thing to their first argu- ment and return the transformed string. BAUDOT CHARACTER TABLE
The following are the characters recognised. As described, the "shift" characters have nonstandard meaning. set Letters Lowercase Figures Symbols code 00 N/A N/A N/A N/A 01 E e 3 Cents 02 L/F L/F L/F L/F (line feed) 03 A a - + 04 Space Space Space Tab 05 S s BELL 06 I i 8 # 07 U u 7 = 08 C/R C/R C/R C/R (carriage return) 09 D d $ * 10 R r 4 { 11 J j ' ~ 12 N n , XOR 13 F f ! | 14 C c : ^ 15 K k ( < 16 T t 5 [ 17 Z z " } 18 W w ) > 19 L l 2 ] 20 H h N/A backspace 21 Y y 6 @ 22 P p 0 N/A 23 Q q 1 POUND 24 O o 9 NOT 25 B b ? delete 26 G g & N/A 27 Figures Figures Symbols Symbols 28 M m . % 29 X x / _ 30 V v ; N/A 31 Lowercase Lowercase Letters Letters COPYRIGHT
