font-weight:light; not working correctly [Sketch issue]

[MaxBazarov]

Ok, I submited a bug report to Sketch. Will keep you informed.

@tijmenvangurp I tried to forget Fontforge dark magic. Because it's a nightmare.
But if I remember correctly — I changed these fields:

[MaxBazarov]

Thanks for the report. I will check it.

Sketch handles font weight selection by UI and by API in slightly different ways.
As a result you can select Light or Thin weight in UI, but in Sketch API both weights are equal (3), so I can't set a valid value.

We met this problem before with other font and the only one solution which we found was to patch the font using FontForge.

[MaxBazarov]

I will continue a research to workaround it somehow.

Another solution is to uninstall Thin and Ultra Thin fonts. In this case font-weight:200 will select Light font.

Do you know what the fix is in fontforge? I am running into the same issue.

@tijmenvangurp I found a workaround for the light Font doing it like this:
font-weight: thin; //thin because light is not working for the moment

That workaround is just working if you don't want to use all the font-weights.

Maybe simple css don't have light font size? https://htmldog.com/references/css/properties/font-weight/

It might be that sketch is following https://docs.microsoft.com/en-us/typography/opentype/spec/os2#usweightclass the OpenType specs? I will try to change the weight names to what the open type has and see if that works.

[tijmenvangurp]

This fix worked for me.
I had to update the name in preferred styles from Xbold to extra-bold then if apply font-weight 800 it works :)

Btw, this fix is only needed for the people in the team using the plugin, since sketch does not see it as an actual different font in use.

[MaxBazarov]

Wow. Great.

In the end, I had to change 3 font-weight names. I followed this table and everything works
