Hello,I'm an Archlinux user.
I'm now having an issue with CJK input method.I could not input Chinese,Japanese,nor Korean languages with linux steam cllient.
I tried some other ways,such as using plasma's Krunner hotkey,to enable me typing CJK language on it,and copy the things I typed,and paste them into steam or games.
And also I heard that Steamdeck can let users typing their language by changing the keyboard layout in steam settings.
So I also wonder if I can use the same way in Big Picture Mode,but I found there is no Chinese,Japanese,Korean language keyboard layout in steam settings.
I tried to reinstall the steam package,but got the same resoult.
So what can I do for it?
Or is it just a bug?
