Re: Re: How do I determine if a string contains non ascii characters

Thanks. I couldn't think of any other sensible way of doing it but I wanted to make sure I wasn't missing anything obvious.
It would have been nice if there was already a pre-defined character class for this though.(since \A and \a are already taken so I suppose \I and \i?)

There is a POSIX macro for this: `[:ascii:]`. That is NOT a character class in and of itself -- it must be used IN a character class: `if ($string =~ /[^[:ascii:]]/) { # a non-ASCII character was found! }` [download] `japhy` -- Perl and Regex Hacker	[reply] [d/l]

Or use the negated POSIX (perlish addition) 'character class' directly: `if ($string =~ /[[:^ascii:]]//) {` -- Hofmator	[reply] [d/l]
