I once opened an issue on his kitty project, asking about right-to-left support. He answered me by saying (falsely, and condescendingly) that the problem was with the CLI apps I ran. But I had screenshotted just typing “echo یک نوشته راست چین” (or sth similar, it was months ago). I, unfortunately, replied to this with a non-respectful (but not rude) comment, which he then answered with another nonrespectful comment and closed the issue. Overall, my impression of him is that he is a kind, productive, but arrogant person; I’m thankful of the man.
