HandleBeforeInput doesn't work when typing in Japanese.

HandleBeforeInput doesn’t work when typing in Japanese. For other languages (En, Ru) it works fine.

Used DraftJS v.0.7.0, Firefox 48.0.2\Chrome 52.0.2743.116, Win7\Darwin In the DraftJS v.0.8.1 also doesn’t work.

handleBeforeInput: function (chars) {
    console.log('Checking handleBeforeInput...', chars);
    return true;
},

render() {
        const {editorState} = this.state;
        return (
            <div>
                <Editor
                        editorState={editorState}
                        onChange={this.onChange}
                        handleBeforeInput={this.handleBeforeInput}
                        spellCheck
                        ref="editor"/>
            </div>
        );
    }

Last week I discussed this with the other maintainers, and we found some issues that will come up with exposing ‘handleBeforeInput’ during a ‘composition’. When a person is entering Chinese, Korean, or other characters with IME input, Draft is building up a “composition” and the DOM is in an uncertain state. We don’t want to allow any interruption until the composition is finished.

We would like to provide examples of how to do the same thing using a different approach - and for this it would be helpful to get specific examples of the functionality you need in the editor.

Is there any update now (11/6/2018)?

HandleBeforeInput is still not trigged for Chinese with IME input on OSX & Chrome 70

This problem also happens with Korean. I think CJK inputs have same problems.
