Windows-1252 doesn't have a character defined for 9D, so when you decode('Windows-1252', "\x9D"), you do something irreversible. The following all result in C3 A2 E2 82 AC EF BF BD.

U+2001 EM QUAD
U+200D ZERO WIDTH JOINER
U+200F RIGHT-TO-LEFT MARK
U+2010 HYPHEN
U+201D RIGHT DOUBLE QUOTATION MARK

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.
