Invalid Character Error

I get the following error message:

Line: 2
Char: 1
Error: Invalid character
Code: 0

I remember running the page in question without any error messages in the past. Moreover, the line in question contains no JavaScripting.

What is the cause of this error and how can it be avoided?

This error seems to be quite unspecific. Now I receive it when I place a page in a frameset. When the page is run directly, not from within the frameset, no error message appears. Any ideas why this happens? The page in question is different from the above example.

P.S. The problem seemed to be again missing javascript source in the newly generated html source. It’s interesting that both the standalone and the frameset versions reported the error when I uploaded them to the above URL. Only the frameset version gives the error when the files are tested from my drive.
