Hi, guys, I encountered a confusing issue during my work. Here it is:

I wanna judge if the string is only consisted of assii chararters, but
without some special characters, like "\n", "\t".

I know I can do this by using two time of match, but is it possible to match
just once?

Any advice would be appreciated.

if ( $str =~ /^[a-zA-Z0-9]+$/ ) {
# $str has only alpha-numberic characters
}
