This is another reason why is_utf8 is a trap. It does not indicate the string is "in UTF-8". It is an internal flag that describes how Perl is internally storing the string. utf8::upgrade and utf8::downgrade enable and disable this flag respectively without any change to the string (as used in Perl code) (as long as the string can be represented in your native encoding, otherwise utf8::downgrade will croak). So in fact, the only sure thing you can determine from is_utf8 is that every Perl string with codepoints above U+FF *must* have it enabled (but not the other way around).

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).
