CREATING A LOCALIZATION READY GAME IN UE4: Part 1 - Text

Hey Sarge,
Are the rumors true, is someone at Epic actively working on adding Arabic support?

If so…
Is there somewhere in the master branch I can view the progress?
Are you using Harfubzz to do the shaping?
Is it going to be released in stages (first text rendering, then text editing) or all in one go?
