Acroread 8 and search with utf-8

Hi, using Acroread 8 in 11.0 and the upfated version in 10.3, is not posible to use ñ,á, and other utf-8 characters in searchs.

Any ideas?

Use kpdf instead or look for an option within Acroread to change the default language.

?? Not really very hepfull

Thanks anyway
