I assume what you want to count is "Graphemes" (see also perluniintro). You should use Perl v5.12 or better; here are a couple of ways (see \X and \b{gcb}, as well as my post here):
my $string = "k\x{0301}u\x{032D}o\x{0304}\x{0301}n";
print "length: ",length($string),"\n"; # wrong way
my $len = () = $string=~/\X/g;
print "len: $len\n";
my @graphs = split /\X\K(?=\X)/, $string;
print "graphs: ", 0+@graphs, "\n";
# in Perl v5.22+:
my @graphs2 = split /\b{gcb}/, $string;
print "graphs2: ", 0+@graphs2, "\n";
__END__
length: 8
len: 4
graphs: 4
graphs2: 4

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.
