I had a sudden problem with Unicode URL aliases. Previously (when I had Community Answers 4.5.* versions), all aliases were encoded normally (there is a corresponding setting in Joomla - Unicode aliases) and correctly.
The title of the article in Joomla - Привет мир, у меня всё хорошо
Now Joomla encodes as /привет-мир,-у-меня-всё-хорошо
See pic: joomla-alias-edit.JPG
And see pic: joomla-alias-list.JPG
But , if I am doing the question in a component Community Answers with the same title CA sets the date as an alias for the replacing: / 91-2019-12-14-17-22-22-09.
It's not correct.
In the pop-up tooltip window when I hover over the word "alias" near the title in the edit ode, I see the following: "Default value will be a date and time if the title is typed in non-latin letters". But why? I have Joomla option "Unicode aliases" in "Yes".

CA - the latest version. 5.0.7.
Joomla - latest, 3.9.13.
By the way, the old versions of Comunity Answers worked perfectly and correctly and did the same as the Joomla with alias encoding. I have already 200 questions + answers and it will be pity to lose this work.
