This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.6.
-----------------------------------------------------------------
[Please enter your report here]
I'm not clear on whether the non-breaking space character (\xA0) is
supposed to match \s or not, but it certainly shouldn't depend on what
other characters are in the string. So this test case:
"\xA0\x{2019}" =~ /\s/ and print "first\n";
"\xA0'" =~ /\s/ and print "second\n";
"\xA1\x{2019}" =~ /\s/ and print "whoops, this REALLY shouldn't match\n";
should either print nothing or both "first" and "second". Under
5.8.7, 5.8.6, or 5.8.4, I get only "first". (I'm sending this from
5.8.6, because I only built 5.8.7 to test this bug, and didn't install
it.)
I discovered this while investigating why HTML::TreeBuilder was
sometimes condensing sequences into a single space. This
turned out to be the reason.
