[Users] Nimbus Sans fonts problem

[edwardp at gmx.com]

Renaud,

I do not have Nimbus Sans L installed, but have the regular Nimbus
Sans. Am using it to compose this and it looks quite nice.

I have seen this in the past, but not with Claws. Generally, with
documents.

At least in the case of this occurring with documents, my understanding
is that whatever font was used to originate it, the receiving system
didn't recognize the font and displayed empty squares instead. I've never had
any font issues myself with Claws.
