           Summary: Sans ExtraLight has a bad kern table
           Product: DejaVu
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Experimental fonts
        AssignedTo: dejavu-bugs at lists.freedesktop.org
        ReportedBy: roozbeh at farsiweb.info


The kern table in the Sans ExtraLight font has the version value set to 1, which
makes it a Mac OS-only table and may lead to problems at least on Windows (and
perhaps on Linux).

See the following two pages:
http://www.microsoft.com/OpenType/OTSpec/kern.htm
http://developer.apple.com/textfonts/TTRefMan/RM06/Chap6kern.html

>From the Microsoft page:
"Apple has extended the definition of the 'kern' table to provide additional
functionality. The Apple extensions are not supported on Windows. Fonts intended
for cross-platform use or for the Windows platform in general should conform to
the 'kern' table format specified here."

>From the Apple page:
"Fonts targeted for the Mac OS only should use the new format; fonts targeted
for both the Mac OS and Windows should use the old format."

I don't know if this is an intended feature or not.
