Working with Adobe Acrobat Reader
We make every attempt to allow our products to be
read and printed reliably by Adobe Acrobat Reader. We have noticed that some versions
of Adobe Acrobat Reader on different platforms may not display our products
correctly. Here are some hints about possible ways to get around these difficulties.
- If you receive the message "Unable to extract the embedded
font..." when attempting to read a file using Adobe Acrobat Reader
on Linux or Unix, then add the line "LANG=C; export LANG" after the
line saying "#!/bin/sh" in your acroread file. The following information was extracted from http://rpms.arvin.dk/pdflib/unpacked/usr/share/doc/pdflib-3.03/readme_unix.txt (which no longer exists) on June 29, 2001:
If you experience the error message "Unable to extract the embedded
font..." while viewing the form under Unix or Linux, you are running into
a bug in Acrobat Reader which affects non-english locale settings.
Workarounds: use a different PDF viewer (e.g., xpdf or Ghostscript), or set
the LANG variable to either "C" or empty before launching Acrobat:
unix> LANG=C acroread PDFlib-purchase-order.pdf
- If your version of Adobe Acrobat Reader does not correctly display ligatures (combinations of
letters that are joined together; see especially the word "confine" on the third last
line of Item (2) in the preface), then you may need to upgrade to a later version of Acrobat Reader. A rather
technical discussion of the problem and possible solutions can be found in the thread following this link.
