"Funny characters" are generaly control characters, in this case the $^foo family of vars. You're seeing $^H as it really is, Control-H, also known as backspace or "". (If you zoom up your font size a bit, you should see that as a block with a circular hole in the middle (reversed bullet), not a "no such character" glyph.) $^H, as perlvar will tell you, gives the hints to the compiler for things like strict and warnings. You're also seeing $^R and $^X -- apparenly the other control-character vars aren't package vars in Main.

Oh, my test script: perl -le "foreach (keys %::) {print qq{$_ -- \\c}.chr(ord($_)+64)}" > foo.txt. Oh, and the \cX is only valid where X is a capital letter. I was too lazy to test for that myself.

Title:
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.
