[pdftex] Links & \pdfannot problems (newlines & width)

[Jörg Ebeling]

Dear Heiko,

the \string and \text.. stuff is exactly what I looked for and is working !
Also your comment to the 8 bit chars is very important for me because I 
also need to use that stuff for Russian and Greek language.

Lot thanks for your help !
