I'm implementing the YAPB into a site I'm working on, and it refuses to validate. Everything past the EXIF information is not seen. When I view the source code, the EXIF information is out putting a whole bunch of these: ���� - which, in my experience, tells me that someone wrote and saved the file in a non-plain text editor. (I see this quite often when someone writes HTML code using Microsoft Word or Rich Text Formats).
I cannot seem to locate exactly *where* this output is coming from, but I have it narrowed down to one of these files: YapbTemplateFunctions.php or ExifUtils.class.php - I think anyway. But re-saving them as plain text doesn't seem to fix the issue. So I'm wondering if it's something else that's causing this.
