( [id://3333]=superdoc: print w/replies, xml ) Need Help??

If you're using locales (which you probably are, if you're dealing with accented characters), Perl's regular expression system is smart enough (usually) to include those accented characters in the \w metacharacter class. You can use this to your advantage. Here's what you need to match:

Any character that is not a nonword character, that is not a-z or A-Z nor a numeric digit, nor underscore. That's a mouthful, but here's how it's written:

print "$character\n" if $character =~ m/[^\Wa-zA-Z\d_]/;

That looks a little ugly, so here's a POSIX version that looks cleaner:

print "$character\n" if $character =~ m/[^[:^alpha:]a-zA-Z]/;

These solutions are not thoroughly tested, as I'm currently sitting at an older operating system that doesn't have much in the way of locale support.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
