Hi, thanks for the contribution 👋
I played a bit with the provided demo and works ok overall. I noticed a bit of flickering when moving around the mouse cursor, not sure if this is platform specific, also the candidate window doesn't seem to follow (how does unix handle this?) - overall not sure how important this is in a real application. I assume 'static' composition windows are more common on text input. It might make sense to adjust the demo a bit to only set the position on click?
Also, please add a changelog entry please for other users to know!

I installed an east asian language pack for testing and it only worked when switching to SM_IMMENABLED here.

I fixed that demo based on your review, and add to changelog. Thank a lot! |

I ran the demo in Windows 10 1809, Windows 8.1, and it worked. |

I am not tested without IME. I followed IMM documentation and implementation will not call IMM API if Windows has no IME.
