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

Fellow Monks,
I should know how to do this, but I don't, so please forgive me. I have some text files with characters whose hex codes are 91, 92, and 97. I want to substitute these characters with other characters. How do I go about doing this? I'm guessing I need to use pack, but I'm uncertain how to do it.

As always, many thanks for your assistance,

davidj

    Your file is in an 8-bit encoding, yes? Make sure perl thinks so too, then use \x for the substitution. 

    #!/usr/bin/perl -C0

# (see -C in perlrun)

# [...]

y/\x91\x92\x97/omg/; # or some other three replacement chars
