No.

Look again at your output

this output is correct, it is *not* a problem...

For the last part of your comment

instead of '\,' which I can't differentiate from '\\,'
[download]

If you would restate that as double-quoted strings it would look like this

instead of "\\," which I can't differentiate from "\\,"
[download]

which is true, but not what you meant, you meant to say (in double-quoted strings)

instead of "\\," which I can't differentiate from "\\\\,"
[download]

which you can and have done.

In a single-quoted string, the backslash ONLY does quoting if it occurs before a ' or a \
otherwise it stands for itself. That's why '\,' and '\\,' actually represent the same string.

Try looking at the printed string instead of the perl form of the string to see what you actually have.

• 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.
