Create an auto-correct software for Windows 10 which will work for Unicode Bengali text -- 2

I need an auto-correct software for Windows 10 which will work for Unicode Bengali text. Microsoft Word’s Auto-correct feature works perfectly fine for Unicode Bengali text, the only problem is it can not be used outside of MS Word. I need a software that will work in ANY app/software of Windows 10 such as typing in Facebook, Messenger, Gmail etc. I have found many such auto-correct software in the internet (including some AHK scripts) but none of them supports Unicode Bengali text. Please only bid if you know how to make your software work with Unicode Bengali texts. Required features: 1. It will correct spelling mistakes based on a list of entries after the space bar is pressed - similar to MS Words auto-correct feature. 2. An easy to use interface to add new words and calling the interface window with a configurable Keyboard shortcut. 3. A way to import BULK auto-correct entries from a .txt or Excel file. 4. A configurable Keyboard shortcut to switch auto-correction ON and OFF as required. 5. An Export feature to export all the auto-correct entries in the software to a .txt or Excel file. Please NOTE: You can also use an AHK script which will automatically support most of the features mentioned above, but it must support Unicode Bengali inputs.
