Bug [#1779]. Better Unicode input support on Windows systems.
- support surrogate pairs in WM_CHAR messages
- support characters from supplementary planes in WM_UNICHAR messages
- support WM_UNICHAR messages in non-Unicode mode
- fix some code duplication
Also, do not return FALSE upon receiving a WM_UNICHAR message with
a UNICODE_NOCHAR parameter, since WM_UNICHAR can actually be handled
just fine (at least with the exact same level of support as WM_CHAR).
