Eorzean Script stroke order

[Zak]

Is there any official source for the actual stroke order on eorzean script characters?
It's stated in a few places that (paraphrasing) "scholars theorize it was written right to left and with a left hand due to shape and stroke order of some characters" so I've been wondering if there's some behind the scenes info about it or it's just (for lack of a better word) "fluff" to explain the characters that kind of "feel wrong" to write by hand (such as F or Q).
