Space was missing from the unshifted codepoint map, so Kitty fell back to the printable character and Neovim saw a plain space instead of the completion mapping. Report U+0020 so legacy mode emits NUL and Kitty emits CSI u, without changing unmodified Space or other Ctrl chords. Co-authored-by: Cursor <cursoragent@cursor.com>
