Hi, welcome to the community!
Try including a head tag in your html like this:
<html><head><meta charset="utf-8"></head>....</html>

Thank you for your reply, but the problem still exists

my charset=“big5”
uipath ver: Studio 2019.10.1
Chinese for example: “龍"

ok, but the problem is visual or the chars are really not ok when you see the html as text?
