At least on recent Windows, the HKL values are a combination of user
selected UI language in the low word, and keyboard layout id in the high
word.

The keyboard layout id used in HKL is sometimes different from its name,
as returned by GetKeyboardLayoutName, in which case it's the "Layout Id"
value in the corresponding registry key under the layout name.
