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.

<Reveal this spoiler or all in this thread> 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 :)	[reply]
