Dear font experts,
I hope it's OK to post this question here. If not, if you are able to suggest a better
alternative it would be great.
It appears that the 'Exo' font from Google fonts has:
Exo-ExtraLight.ttf: <usWeightClass value="250"/>
Exo-ExtraLightItalic.ttf: <usWeightClass value="250"/>
Exo-Thin.ttf: <usWeightClass value="250"/>
Exo-ThinItalic.ttf: <usWeightClass value="250"/>
So I'm wondering--are duplicate usWeightClass values for different font weights:
* Permitted, but non-standard?
* Permitted, but completely abberant?
* Permitted, but likely an inadvertency on the part of the font creator?
AFAICS, as someone at least 100 km from being a font expert, I'm guessing the above
usWeightClass scheme is not supported in CSS or by browsers? (This is not actually my
context. It's more to do with the font file selection process for font families and
preferred font families. A miasma.)
Many thanks for any advice or comments.
With appreciation for a great forum,
