Hi. Looks like current implementation does not support different keyboard languages.

For example if I register shortcut with English keyboard, everything working good (even after language change). But when I register shortcut with non-English active keyboard (Ukrainian for example), shortcut doesn't get registered.

After some debug, I found that the reason of the problem is in the VkKeyScan function:

This function always return -1 if current active keyboard is non-English.

As documentation said:

Translates a character to the corresponding virtual-key code and shift state for the current keyboard.

If the function finds no key that translates to the passed character code, both the low-order and high-order bytes contain –1.

So this function is dependends on the current active keyboard and should be replaced with to something else.
