neovars: unicode keypress replaced with native send

Notes:
- "SendUnicodeChar(charCode)" can be replaced by send % {Chr(charCode)}
  since AHK 1.1.27; this should produce similar results
  (compare with SendUnicodeChar in  522e83eee0/source/keyboard_mouse.cpp (L91))
- however "up", "down" events cannot be replaced similarly for most keys
