I wouldn't expect to find anything useful there (that logic is in the
library itself).

Using fc-query, it reports the same weight value for Light and Extra
light fonts (50). Looking into the fonts OS/2 table, the Extra Light has
weight value of 250 (not sure about the exact relation between FC weight
and OS/2 one) while FontForge's predefined values suggest 200 for Extra
Light, which corresponds to OS/2 table documentation:
http://www.microsoft.com/typography/otspec/os2.htm#wtc

So I'd say it is a font bug (might be a FontConfig limitation as well, I
have some vague recollection about some discussion somewhere on whether
OS/2 weight must be multiples of 100 or not).

fc-query reports Black weight not Heavy.

(I didn't installed the fonts, just using fc-query on the downloaded
files).
