Adobe acrobat reader 7.0 Benutzerhandbuch

 

You can work with Adobe PDF files that contain Cyrillic text (including Bulgarian and 
Russian), Central European text, and Eastern European text (including Czech, Hungarian, 
and Polish), if the fonts are embedded in the PDF files. If the fonts are embedded, you can 
view and print the files on any system. Fonts do not need to be embedded to use the 
Search feature.

Note: If you open a PDF file in which form fields or text boxes contain these languages 
but the fonts are not embedded and are not installed on your system, the Updates 
command automatically prompts you to download and install the necessary language font 
kits.
