"Looking" at the characters of a Unicode string.

Description: Recently, I was stumped by "strange black boxes" appearing in a Win32 application textfield, whose contents are retrieved from a Unicode database field.

I used the following snippet to help me identify what was a "bad" mix sequence of <CR> and <LF> characters.
use Unicode::CharName qw/uname/;
use Unicode::UCD qw/charinfo/;

my $value = <what you are looking at>
my $c;
print "Unicode Charname:\tHexValue:\tCharCode\n";
for (split //, $value) {
  $c = ord($_);
  print uname($c) .":\t" . charinfo($c)->{code} . ":\t$c\n";
}

    Nice. I modified my copy to display the letter, and reversed the print string so that the long text of the unicode name didn't muck up the tab columns.
    #!/usr/bin/perl use warnings; use strict; use Unicode::CharName qw/uname/; use Unicode::UCD qw/charinfo/; my $value = shift || "Å være eller å ikke være"; my $c; print "HexValue:\tCharCode\tUnicode Charname:\n"; for (split //, $value) { my $l = $_; $c = ord($_); print charinfo($c)->{code} . ":\t\t$c\t\t"."$l -> ". uname($c) ."\n"; }

Corion idly wonders about creating a series of HTTP requests. There seems to be no framework to generate a series of HTTP requests, like "try all these requests"
[Corion]: This is vaguely inspired by that list of "nasty" strings, which I'd like to replace among HTTP parameters, just to see whether the application crashes, but also for easy downloading of a list of URLs etc
