I am Japanese and used to use Japanese and English characters togeter. When I copy text from some program to chromium-browser in-box, it garbles. Garbles (mis-conversion) happens between some program and chromium but not happen inside chromiums.
For example, I open text editor(leafpad) and type "abcあいう" and copy this, then paste it some inbox(URL/Search box) of chromium, it garbles like: abc\u3042\u3044\u3046 * but not garbles inside chromium themselves.
My chromium version is 88.0.4324.187 (Official Built) on Raspbian. I guess this happens recently but I never experienced before. Same thing above between Firefox and leafpad works.
Thanks, Shigeru
