Down and dirty hacks are available of course. For everyday use I have come up with this:
#!/usr/bin/perl
use locale;
my @list = ('maceira', 'mac alister', 'mac loughlin', 'san esteban', '
+sangregorio', 'san zoilo');
sub keeping_spaces {
my $aa = $a;
my $bb = $b;
for ($aa) {
tr/ /A/;
}
for ($bb) {
tr/ /A/;
}
return $aa cmp $bb;
}
print "$_\n" for sort keeping_spaces @list;
Which outputs what we would expect:
mac alister
mac loughlin
maceira
san esteban
san zoilo
sangregorio

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).

or How to display code and escape characters
are good places to start.
