Why doesnt my fonts work when publishing to PDF?!?

Hello,

I´ve an interesting problem;

When I publish a single-page PDF from my drawing, Arial font works ok, but when I publish the same exact file as a multipage document (ALL the settings are the same both ways), some of texts do not work. They display as lines of dots, what the ?????

I´ve tried to publish the file, batch plot, use sheet set to publish, changed printing from Adobe PDF to DWG to PDF and vice versa. None of these works.

Single page PDF plotting works every time, why not multipage publishing?
