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

And one other thing that I'm finding conflicting advice for on the internet is packing the incoming data from CGI into utf8.

I currently use:

$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;

against the strings that come in via the web.

Now I see that there's a "U" template for unicode. But I'm after UTF8, so that doesn't quite fit, and I don't understand what the pack docs are saying about UTF-8. However, in a couple of places I've searched I've found this:

$value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg; utf8::decode($value);

which I don't really understand. I'd assumed the "C" would put everything into ASCII/ISO-8859-1 and utf8::decoding that would just produce garbage out of the special characters.

What would the monks advise?

Cheers

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).
