Bug in Firefox. It should work as you describe.
As for the composition: first of all, work on characters, or at least or codepoints, not on utf-8 bytes. Second, you want Unicode Normal Form C (see Unicode::Normalize), so that you can write:
use Unicode::Normalize;
use charnames ':full'; # this is just to make things easier in this ex
+ample
binmode(STDOUT,':utf8'); # this to make 'print' output utf-8 bytes
my $a="O\N{COMBINING DIAERESIS}";
my $b=NFC($a);
print length($a),$a,"\n";
print length($b),$b,"\n";
Will print:
2Ö
1Ö
(more or less, depending on PM's escaping mechanisms)

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).
