best way to search

[Flynn, Timothy J]

Hi,

        What is the best way to search for all printable characters.  i.e..
I want to eliminate any characters such as \n\r etc.

Is it best to return what you want to see.


$somestring =~ s/[^0-9a-zA-Z]//g; 

or 

$_ = $somestring;

s/[\n\r]//g;


I want to keep the spaces.

Thanks!

-Tim
