Either Reader tries to substitute the misisng fonts with the nearby sub font, or you would see a row of dots appears in the lines of text that contain the missing symbol.

Hope this helps !!!
Thanks for the link - very interesting.
However I am very puzzled about Helvetica.
Most PCs do not have it as it is expensive and yet most organizations use it in their PDFs (from my experience).
So as far as I can tell it is substituted by ArialMT (File>properties).
Any comments anyone?
Sorry but I do not fully understand.
Are you saying that if the organizations embed Helvetica then Arial MT will *not* be used as a substitute.
By organizations I am referring to banks, gas suppliers etc.
BTW how can I tell what fonts have been embedded in a PDF.
Europe, Middle East and Africa
