One way to verify what Perl is really storing internally is Devel::Peek. What I would look for is that the UTF8 flag is on, and the string when shown as UTF-8 is correct:

use Devel::Peek;
my $str = "\x{20AC}";
Dump($str);

__END__

SV = PV(0x15c0d70) at 0x15e0440
  REFCNT = 1
  FLAGS = (POK,IsCOW,pPOK,UTF8)
  PV = 0x15e4e10 "\342\202\254"\0 [UTF8 "\x{20ac}"]
  CUR = 3
  LEN = 10
  COW_REFCNT = 1

Here, [UTF8 "\x{20ac}"] is correct. There's also utf8::is_utf8($str) to check for the UTF8 flag, although I'd recommend only using that for debugging as well. If you don't want all the extra output, you might just say:

use Data::Dump;
my $str = "\x{20AC}";
dd $str, utf8::is_utf8($str);
__END__
("\x{20AC}", 1)

Are you posting in the right place? Check out Where do I post X? to know for sure.
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).
Want more info? How to link or How to display code and escape characters are good places to start.
