Within "perluniintro.pod" I found this:

Note that \x.. (no {} and only two hexadecimal digits), \x{...}, and
chr(...) for arguments less than 0x100 (decimal 256) generate an
eight-bit character for backward compatibility with older Perls.  For
arguments of 0x100 or more, Unicode characters are always produced. If
you want to force the production of Unicode characters regardless of the
numeric value, use pack("U", ...) instead of \x.., \x{...}, or chr().

This explains why "\x{f6}" won't produce utf8 output.
Nonetheless the pack( "U", hex( "f6" ) ) I used originally should spit out a two byte sequence, shouldn't it?

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

  • 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.
