I just reported the first bug for VisualEditor handling non-Latin text:  https://bugzilla.wikimedia.org/show_bug.cgi?id=44442

I am certain that there are others to be found!

Hi, now it's confirmed and ready for distribution:

Next week we are going to focus on testing VisualEditor in conjunction with non-Latin scripts: العربية, Ελληνικά, 한국어, हिन्दी, עברית , 日本 語, Русский, 中文 and more.

https://www.mediawiki.org/wiki/VisualEditor/Testing_Non-Latin_Characters_Input_and_Behavior

The testing will be done at the English Wikipedia (primarily in User pages), where VisualEditor can be enabled. Any editor can contribute, regardless of testing / technical experience and even knowledge of languages in those scripts. For instance, copying texts from http://ru.wikipedia.org/ or http://ja.wikipedia.org/ and playing with them in your User page is also a good starting point.

Of course we welcome the participation of editors from projects based on non-Latin scripts. Your help as ambassadors connecting with your communities is especially needed! A main incentive is that good testing coverage of VisualEditor in a specific script plus good community involvement might lead to its inclusion in the related Wikipedia(s) for broader testing.

If you have any questions or feedback please comment at
Talk:VisualEditor/Testing Non-Latin Characters Input and Behavior or send me an email. Thank you!
