Terminal Chars are ALWAYS UPPERCASE on MacOSX when 'keyboard Caps on'

[lxx2013]

Issue Type: Bug

Mac's default style of 'UpperCase or LowerCase' is widely-known as follows:

1. when 'Caps off && Shift off', It maybe 'Chinese IME'
2. when 'Caps on && Shift off', It is 'English LowerCase mode'
3. when 'Caps on && Shift on' , It is 'English UpperCase mode'

But the terminal in the vscode of version 1.31.1 didn't display correctly at scene 2.

VS Code version: Code 1.31.1 (1b8e830, 2019-02-12T02:16:38.656Z)
OS version: Darwin x64 17.5.0, OSX 10.13.4

Other terminals do this too.

[lxx2013]

Well, Mac's default Terminal.app and iTerm2 won't do this. Disappointed at your reply.

Ah I wasn't reproducing the right thing, this appears to be specific behavior of Chinese IMEs. Repro:

1. Enable PinYin IME
2. Type (Chinese auto completions appear)
3. Caps lock on
4. Type - This should be lowercase in the terminal but it's uppercase

i have same issue(Japanese IME
it appeared after updating latest MacOS

MacBook Pro (13-inch, 2017,
Mojave 10.14.3
code 1.31.1 (1.31.1)

My problem is fixed

1. Open keyboard settings -> input source
2. set "CapsLock behavior" as "input Alphabet when CapsLock is Off"

thx.

I tried to set terminal.integrated.setLocaleVariables to true or false. It doesn't work.

My OSX version is 10.13.4. My Chinese IME is Baidu IME for Mac

@henpin Brilliant

Regarding #68865, @henpin's solution works fine for macOS's default Chinese input source ,but not for Sougou input, a 3rd party input source which is the most popular Chinese input.
