Is this font missing appostrophe or something else is wrong?

[Arthur Miller]

I have been using Anonymous Pro for quite some time mostly because it is
programming friendly, has math symbols as well as lating and greek
symbols plus some other stuff.

Today I have noticed in info files that some characters are not rendered
properly. I haven't noticed this before, but I have rebuild Emacs from
master today.

Seems to be the '‘' character. I have attached a screenshot of how it
was rendered. 

Font is OFL (open font licence) and can be seen here:
