Instant crash on Apple's devices

Hello guys,

A group of Russians just discovered a new bug on Apple's pltaform. I just experienced too. The bug is: the instant crash on any Apple plataform (Mac OS, iOS) when you read some persians characters.

For example: Anyone on your facebook timeline posts the sequence of persian characters, and Safari immediatly crashs.
Same thing on iOS, if anyone post on Twitter, or Facebook, you won't be able to use them.

Couple of people just posted on my Facebook timeline and it's really annoying when you're scrolling your timeline and suddenly Safari crashes.

Did you hear/experienced that?
From where I heard, Apple knows this bug for 6 months and nothing has changed though.
