Re: Are there css engines that cannot synthesize oblique fonts?

Hi,

WeasyPrint, for example, does not synthesize oblique and bold fonts. 
There’s no real technical limitation to add the feature (WeasyPrint 
use libraries that can do that), but it’s never been necessary so 
far: users are generally happy when they’re explained that they 
should use real italic / bold fonts instead to get better result.
