I don't know if they are truly "valid, printable characters". When a text file show this type of information, isn't ascii just approximating some binary data?
Why I think this is if I open with notepad I get a file that looks like the: ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ described earlier but if I do a simple: Perl -ne "print" test.msg I get only a single: ╨╧◄αí▒ (btw this is the same output I get when I do a: c:\type test.msg) Even if I wanted to define a character class like [a-zA-Z] how would just extract these characters?

I suppose one way to go would be to create a character class with all of the characters that you want to allow. Something like the following: [a-zA-Z0-9_-=()\[\]\\\/'";:><?.,!@#$%\^&*+] (You might have to fiddle with the escapes a little) and then you could do a tr/// or s/// to filter them out. -----Original Message----- From: Tim Booher [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 5:37 AM To: [EMAIL PROTECTED] Subject: use perl to trim out non text characters from a file Hello – this should be really simple to the learned perl programmer, but I am trying to create a simple script to trim all the ‘junk’ out of my email files. I get a lot of suspicious emails in outlook and normally drag them to the desktop and open with notepad. This works, but most of the message is the following: Ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ Does anyone know what regex could I use to only select all text and trim all the ‘junk’ from the msg file? Also, does there exist a script already to do this that you know of? Thanks, Tim
