Same problem in last Blender 2.79 nightly build and last Blender 2.81 nightly build (August 28, 08:55:54).
Short description of error
In Blender Preferences (Keymap), wrong keys are indicated when registering new shortcuts.
Exact steps for others to reproduce the error
I use a Corsair keyboard (with French layout) with my laptop (which has a UK layout).
I use the "French keyboard Windows input method" when typing on the Corsair keyboard.
In Blender Preferences, then Keymap, then any shortcut: when I click in the "Type of event" box and I type with my French Corsair keyboard on a new key to make it the new shortcut, it is not the key that I typed that is indicated.
This is the case for many keys (basically, all the keys for punctuation marks and accents).
For example, when I type the "!" key, it is indicated "F13" instead of "!".
Note that when, for example, I want to change the name of an object in the Properties panel (still with my French Corsair keyboard), there is no such problem: the characters written are exactly the characters that I typed.
