Just checked out Arabic support in 3.0 (build ade39f5). The letters are currently rendered LTR.

Closing this due to the age and most of those being fixed.

@akien-mga
You added this to 4.0, but you forgot to reopen.

Thank you.

[akien-mga]

There's nothing to reopen, all issues on this tracker are closed.

Okay, sorry.
