PDF docs looking fine on one computer and totally messed up on another is many times caused by using a non-standard font installed on the computer where it looks fine.

The remedy is to embed the font characteristics and glyph info inside the PDF itself, but that may balloon the size of the PDF, unless you provide the font to the user (then they install it themselves).

I can’t even get Yahoo mail to render properly on Google Chrome. Shows up as tiny font.
