RTL LTR Function

[ghost]

When you try to write an RTL Language the line "Or the Block" should be providied direction: rtl for correct rendering.

There should be an option for choosing direction, I tried to hard code the RTL, and pen meet my expectations "I think there's no bugs in selection or reading or mixing rtl with ltr words".

Major RTL Text : Arabic/Farsi , Hebrew , Thai.
