FCKEditor's parsing of plug-in files and regular expressions

Hey,

I have an interesting problem and the only thing I can think of is it is caused by the loading of plugin .JS's by FCKEditor.

A very basic example of this would be the following snippet from a plugin JS:

var html = 'abcdefgh 12345678';
var re = new RegExp('\d', 'gim');
var m = re.exec(html);
if (m == null)
{
   alert("No match");
}
else
{
   var s = 'Match at position ' + m.index + ':\n';
   for (i = 0; i < m.length; i++)
   {
      s = s + m[i] + '\n';
   }
   alert(s);
}

The following code will match on abc -> d <- efgh 12345678 instead of abcdefgh -> 1 <- 2345678. I am assuming that since this file is loaded from an external JS into FCKEditor it is somehow deleting the \ before the d and thus turning that regular expression into:

var re = new RegExp('d', 'gim');

If you escape the regular expression it works and successfully matches abcdefgh -> 1 <- 2345678:

var re = new RegExp('\\d', 'gim');

Has anyone ever encountered this before?

I am using:

- IE 7.0
- FCKEditor Version 2.4.3
