Need feedback to this one. I had to substitue -latin- with -all- for fixing the non latin fonds.

But there are no woff2 files for -all- so I removed the links to woff2. Reading about this woff2 seems to be the preferred format. Any better ideas?

As long as it's supported by electron it seems fine by me.

tested this with electron, but must be tested anyway by non-latin users ...

During standard web-developmet, woff2 would indeed be preferred due to size improvements. But I guess here we can ignore that :-)

I merged this to see if this will cause issues. We can always revert if someone runs into issues.
