Enable IME in inputtext

[shota-inoue]

Is your feature request related to a problem? Please describe.

I would like to use inputtext, but my expected native language is Japanese. Japanese is already supported by Babylon.js, IME cannot be used in inputtext because IME is not working.

Describe the solution you'd like

In the discussion, RaananA was able to input Japanese in a pseudo manner by using the native input field as one of the solutions. However, I want to input Japanese using IME with inputtext without displaying the native input field.

For future reference - IME (Input method editors) - https://docs.microsoft.com/en-us/windows/uwp/design/input/input-method-editors are a standard way to input many different languages while still using an english-layout keyboard. The input to the text field is still english (and is being converted while typing). Language like Japanese and Chinese are using it, and they are supported in a native input field.

Perhaps an HTML element input cover virtual input, is a better general solution.

we cannot use solely an HTML element, as Babylon native doesn't support HTML elements. We will need to consider a more abstract solution, though it seems like we will eventually be forced to use an HTML element, at least for the web version

No traction. Might be re-open if IME is supported in the Canvas API
