You are right. It turns out that kerning is disabled in Windows by default. Unbelievable.

And you are sure that Windows actually applies kerning?
Can you show a screenshot with and without kerning?

Maybe it does not mean anything, but this same font is displayed perfectly in Windows.

This looks like a bug in the font.

For example, ttx reports 28018 font units for the kerning
value between `N' and `o'. FontForge reports this value too.

Given that the `m' is about 1000 font units wide, FreeType
seems to do the right thing.

With the attached font, FreeType reports very large kerning values, several orders of magnitude larger then expected.

The problem can be reproduced with the following command:
ftstring -m 'No' 10 barth_n.ttf
Pressing 'k' will turn pair kerning on, and the letters will jump away from each other.

Tested with both 2.2.1 and 2.3.4.
