How do I remove invisible “  ” which has been automatically added to code in JQM?

I am developing a mobile website in JQuery Mobile and I am fining that at seemingly 'random' points, the web browser is adding in:

"        "

(different amounts on the different pages it occurs).

Much of the base of the code is copied and pasted straight from the JQM demo site for the different widgets/layouts etc... and I have read that copying/pasting code from different places can cause this issue. The problem is, how do I remove it, especially when I have already done a reasonable amount of coding?

I have tried copy/pasting it into notepad, saving as a plain text doc and then copy/pasting back into my editor (Sublime text 2) but that doesn't seem to work.

I'd prefer a procedural solution over having to add a line of script to strip it out at the browser end if possible.

An example of this can be seen on this page: http://noee.brandallareas.co.uk/#delegates , There is not meant to be that much space between the tables (you can see the added space characters through firebug/element inspector).
