Re^2: hex in regexp

Sorry, I did not understand your answer at all. You see, I just started to learn Perl and sometimes may not recognize the value of the example shown. My task is to get rid of the non-Ascii symbols which were mixed with Ascii symbols in text file with multiple rows. I am not sure that solutions mentioned in the first reply do the trick. (what is the meaning of $freeStuff and $stuff anyway...). Could you please provide more vivid example or direction.

That is the great thing about code, you can try it out, and see if it meets your needs

See, I assumed an XY Problem . I assumed what you really wanted to do was use an already existing encoder/serializer, instead of inventing your own, so I showed you two which use hex encoded characters. One which only does strings (CGI->escape) and one which does complex data structures (JSON)

I guess since this might be homework a practical solution doesn't fit :)
