Describe the bug

I'm writing an english command then I swap to the Japanese keyboard and I'm not able to see the characters as I type them out. I tried the Dark theme and Dark City theme without success. It also did not appear to that the characters were just hidden as even entering correct input did not result in the command being successful.

I saw two other tickets related to this that are closed, but this is still an issue.

To reproduce

1. Type a command like cd
2. Switch to Japanese keyboard
3. Characters fail to output

Expected behavior

Should be able to type Japanese characters just like regular English characters. Should just be utf-8 right?

Found a workaround.

You can type the Japanese characters and you won't be able to see them as you type, but then you can switch the macOS keyboard back to English and the characters will appear. You can then tab complete or just press enter like normal.

Not ideal for every scenario, but usable.
