Acrobat Reader is only offered in English on UNIX based platforms, and errors may be returned when attempting to open PDF files with language locales other than English. These errors suggest font access or extraction problems with the PDF file, but are actually due to the fact that the English Acrobat Reader cannot function correctly within a UNIX non-English language locale.
To view such PDF files, switch to the English locale by performing one of the following steps before launching the English Acrobat Reader:
LANG=C;export LANG
This approach will ensure correct behavior when Acrobat Reader is launched by other applications, such as Netscape Navigator, or an application help menu.
