--- Comment #3 from Fujii Hironori <Hironori.Fujii at sony.com> ---
Firefox implementations looks quite complicated. I can't understand them.

Firefox also has the similer code to build a mapping table by using ToUnicodeEx in KeyboardLayout::LoadLayout.
But, I can't understand how this table is used.

It seems that Firefox is mapping a key code by using the following WM_CHAR events for printable keys,
and a hard-coded table for non-printable keys.

NativeKey::GetFollowingCharMessage retrieves queued WM_CHAR messages for printable keys.

KeyboardLayout::ConvertNativeKeyCodeToKeyNameIndex is converting non-printable keys.
https://dxr.mozilla.org/mozilla-central/source/widget/NativeKeyToDOMKeyName.h is the hard-coded table.

842927 - Implement DOM3 KeyboardEvent.key only for non-printable key, first
