[PATCH 0/2] MR1992: user32/edit: Fix WM_CHAR handler for double-byte characters.

[Akihiro Sagawa (＠sgwaki)]

After commit 2aa54a90, a double-byte character is sent to the edit control by double WM_CHAR messages. However, its WM_CHAR handler (ANSI version) can't process a double-byte character properly because the handler converts WM_CHAR to WCHAR one by one.

This fix queues the double-byte lead byte as it comes in and then uses it afterwards for the WCHAR conversion.
