Arabic type settings mixed with Latin characters looks to be wrong #567

Closed GaetanBaehr closed 4 months ago

GaetanBaehr commented 4 months ago

In Drawbot if the Arabic text starts with a Latin word, the Latin word appears at the wrong place, here on the left, but it should be on the right.

In text edit at first it behave the same

but if we change the writing direction to right to left, then the text is correct

As far as I know, in Drawbot looks to be impossible to change the writing direction.

Yes, maybe we need a writingDirection() function or something like it. I'm not sure how this should work internally.

CoreText has support we can wrap: https://developer.apple.com/documentation/coretext/ctwritingdirection?language=objc

justvanrossum commented 4 months ago

Can this be part of our language() function, or do you think it's better to add a new API function?

typemytype commented 4 months ago

well a writingDirection(direction) sound good and explicit...

with direction options:

It could possible be automated related to language('ar') but then we need to find out what the language direction is...

It is probably best not attempted as a single language can be written in two scripts with different directionality, e.g. Uzbek. But if you wanted contemporary defaults and used only the 2-letter codes, there are not that many…

true, @MrBrezina I prefer an explicit api, no magic guessing
