Hi,
What I'd really expect, regarding RTL text alignment, is that the alignment would be per paragraph. Other iOs applications (e.g. Notes, Mail, Gmail) work this way. And it does not seem related to any specific iOs version.
By "per paragraph" I mean that if the paragraph begins with English/Latin characters, make it align LTR.
And if it begins with an RTL (e.g. Hebrew) character make it align RTL.
Beyond that iOs allows you, when you select a text, to manually determine its alignment.
So the RTL alignment issue need not be per file or per the whole application. Just per each single paragraph. Each paragraph and its own RTL/LTR alignment.
Thanks
