datlechin sorry I was wrong. It seems like it's sth relates to PWA. When I use copy links in PWA mode, the CJK characters in links would automatically recoded to
%E9%80%9B%E8%B8%A9%E7%BB%84%E5%88%B7%E5%88%B0%E4%BA%86%E4%B8%80%E4%B8%AA%E5%9C%A8%E7%BA%BF%E6%96%87%E6%A1%A3%E8%A6%81%E7%AC%91%E6%AD%BB
it works perfectly in browser mode
