This is only an encoding output layer / character encoding mismatch. It should be solved with proper layers, not hacks.
moo@cow[6]~>perl -le 'print "\x{263A}"'
Wide character in print at -e line 1.
☺
moo@cow[7]~>perl -CSD -le 'print "\x{263A}"'
☺
# OR
moo@cow[8]~>perl -MEncode -le 'print encode_utf8("\x{263A}")'
☺
# OR
moo@caow[9]~>perl -le 'binmode STDOUT, ":utf8"; print "\x{263A}"'
☺
# OR
moo@cow[10]~>perl -Mopen=:std,":encoding(UTF-8)" -le 'print "\x{263A}"'

This is in a UTF-8 aware terminal. These things RFC:MUST line up at every level to be correct: input, processing, output. There are no shortcuts and there is no need for hacks or special functions if it’s done properly.
Unicode and character encoding issues are difficult at first and messy but they must be understood or else it’s generally an accident or luck when things appear to work. Related reading–

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).
