If X Y and Z can legitimately be in the file you are going to have to do more work. Keep track of values that you have "fixed" substitutions in, and what the original character was. You will then have a list of 'known suspect values' as well as a way to get the original value.

The best approach (short of retrieval from a backup) would be to do as much parsing and sanity checking on the data as you process the file. Trivial/Obvious fixes can be automated, but anything questionable needs to be flagged and ask for human intervention.

Good luck. I think you'll need it :/.

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.
