So you end up with: 

sub is_vowel {
    return $_[0] =~ /
        ^
        [\x{1F00}-\x{1FE3}\x{1FE6}-\x{1FFE}\x{0386}-\x{038F}\x{0390}\x
+{0391}\x{0395}\x{0397}\x{0399}\x{039F}\x{03A5}\x{03A9}\x{03AA}-\x{03B
+1}\x{03B5}\x{03B7}\x{03B9}\x{03BF}\x{03C5}\x{03C9}-\x{03CE}]
        \z
    /x;
}

There might be a better way of doing this, but i don't have time to research this right now.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:

    < &lt;
    > &gt;
    [ &#91;
