Hi darkskyex, thank you for taking the time to report this bug!
I have been unable to reproduce this issue In my testing, but I'm not familiar with Cantonese input methods, so I may be misunderstsanding some key details. When I tried, the Cantonese suggestions appeared after the first letter. I am wondering if in your case the suggestions are hindered by the URL autocomplete?
See in my screen capture, whn I start typing the first s, I see Cantonese suggestions right away, however when I start typing ens, it first tries to autocomplete en.wikipedia.org.
Please let me know if there's more information that would help me better understand the issue?
Thank you for your help in making Orion a better browser!
