Problem Description:
--------------------
When trying to insert non-alphanumeric characters in a string
such as "\" it becomes necessary to back quote them. This
works fine, for example "\%" becomes "%" in the database, however
a "\\" stays as it is. THis makes it impossible to ever end
up with the text "\*" in the databse. If you try the logical
"\\\*" to do that, it results in "\\*" which is not what I wanted.

--------------------------------------------------------------------------

Test Case:
----------
Try inserting any data in the above format.

--------------------------------------------------------------------------

Solution:
---------
Fix the function wich un-does the back quoteing.
