I just came across a curious display error and was wondering what may cause it.

In Safari the following webpage Cross-Country Skating: shows a strange behaviour.

But the source code does not show this error:

... America’s Bill Koch first observed ...
... climaxing in a telegenic finish ...

Neither does Google Chrome:

Can anyone explain this behaviour?

MacBook Air (MacBookAir3,1)
Intel Core 2 Duo; 1,6 GHz

OS X 10.11.2 (15C50)

Safari Version 9.0.2 (11601.3.9)

It's an official bug, yes. It seems to be solely happening with Merriweather Sans.

Maybe someone at Apple or on the east coast decided to protest the name of the font? ;)

Seriously, an update is in the works, and someone here suggests a work-around.



This is probably a problem with Safari font rendering engine with Merriweather Sans font. It has something to do with ligature I suppose. You can check typecast.com and see that when You insert fi it automatically is changed to if as You type.

  • I thought so too. The error occurs throughout the article ligatures might be the combining factor. But do you have an idea what causes this ligature misrepresentation?
