I suggest you first try with the table we already created, i.e., namesutf8 with utf8mb4 charset.
In the same table, please try to enter Chinese characters and save and test. After this test, we can try other variants.
I do not know Navicat tool.
But I am able to copy from webpage and paste any known language in this table
This table contains 6 languages. We are able to input, edit and view 6 languages at the same time. I entered 4 Indian languages from my keyboard using Google Input tools and 2 languages Chinese and Thai are copied from Web and pasted.
When it is possible to handle all these languages with ADO, I think it should not be a problem for using for Chinese or Thai
