Replacing characters in file names is just plain wrong in Unix. A space is a space, and not something else. And something that isn't a space, just isn't.
#!/usr/bin/perl
use 5.010;
use strict;
use warnings;
my $dir = "/tmp/Foo";
mkdir $dir or die;
chdir $dir or die;
opendir my $dh, $dir or die;
my @files = readdir $dh;
closedir $dh;
say "Got ", scalar @files, " files";
foreach my $char ("\x{20}", "\x{A0}") {
my $file = "foo{$char}bar";
open my $fh, ">", $file or die;
}
opendir $dh, $dir or die;
@files = readdir $dh;
closedir $dh;
say "Got ", scalar @files, " files";
__END__
Got 2 files
Got 4 files
See, two different files - one with a space, the other with a non-breaking space. No automatic conversion between them.

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).
