Safe non-display;print characters.

Steve_BZ has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

I have an application which contains free text and I would like to embed some automatic fields in it (think fields in MS Word). I'd like to delineate those fields with some sort of non-display character. Is there a list of ctrl-characters in Perl, what they are used for and which ones are safe to use?

Have a good day.

Steve.

Perl doesn't care. The question should be: this application, what non-display characters can it accept? CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James	[reply]
