Re: converting smart quotes

You have a utf8-encoded string. You need to convert it to Perl's native Unicode string format (which also happens to be utf8-encoded internallly, but marked with a special flag such that multibyte sequences are treated as single characters).

You can do this like:

utf8::decode($string);

The utf8::decode function works in-place (like chomp), so you can just call it in a void context.

That said, you won't find a \x92 character on the page you linked to, because there is none. There's a \x{2019} character though.

The following takes the page content, and makes ASCII control characters and non-ASCII characters visible.

use 5.010001;
use LWP::UserAgent;

my $url     = 'http://publib.boulder.ibm.com/infocenter/brjrules/v7r0m
+3/basic/tocView.jsp?toc=/com.ibm.websphere.ilog.jrules.doc/toc.xml';
my $content = LWP::UserAgent->new->get($url)->content;
utf8::decode($content);

$content =~ s { ([\x00-\x08\x0B\x0C\x0E-\x1F\x80-\x{1FFFFF}]) }
              { sprintf('[U+%04X]', ord($1)) }gex;

print $content;
[download]

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

`my $content = LWP::UserAgent->new->get($url)->content; utf8::decode($content);` [download] can be replaced with `my $content = LWP::UserAgent->new->get($url)->decoded_content;` [download]	[reply] [d/l] [select]

In this case, yes, but `decoded_content` does a lot of other stuff besides. Also I wanted the OP to have a better idea of what's going on - that when Perl gets data from the outside world it's often in bytes, which need decoding into Perl's native Unicode representation. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l]

In this case, yes, but decoded_content does a lot of other stuff beside Stuff that must be done, such as removing compression when used.	[reply]
