The ime-mode property is also very problematic for this purpose:
1. Activating/deactivating the IME is a very special concept only available
on Windows, and may not suitable for other platforms.
2. "disabled" makes no sense for this purpose.
3. IMO, it's more like a hint instead of a mandatory restriction. The user
should have right to override it.

So for this purpose, I still think having an explicit attribute to hint the
desired character set of an input element is better than ime-mode solution.
So that the UA can decide the proper action for it.
