I apologize for my delay in following through on this. A separate project deadline has come up.
But I've downloaded Notepad++ and have saved the files using ENCODING > SAVE TO UTF-8 WITHOUT BOM. I'll test them.
I never knew a problem such as this could exist. I'm going to have to rethink my naive use of regular Notepad for saving files. (Already got caught saving an XML spreadsheet in ASCII instead of the UTF-8 option).
Thanks for everybody's input.
