PHP SQL error caused by the character "-"

    Hi all

    Have any of you seen this before?

    The character "–" (not to be confused with a regular hyphen, i.e. "-") causes a SQL error if it is used in a query executed by mysql_query in PHP. It does not cause an error if you use it directly in phpmyadmin.

    I have no idea why this character causes a problem. As far as I can see it is not a double hyphen so should not be treated as the start of a comment.

    Do you know of any other funny characters like this which can cause SQL errors?

    Note mysql_real_escape_string has no impact on this character.

    Cheers

    Maybe its an encoding conflict? What encoding or environment did you get or create the dash in and into which encoding are you trying to insert it into?

    That's it exactly. It looks like the character came from Word (Windows-1252) and I am using UTF8.

    I just changed my code to be Windows-1252 aware and the character is now allowed.

    Thanks for the advice.
