You can request character input from text buffer and text grid windows. See
evtype_CharInput. There are separate functions for requesting Latin-1 input
and Unicode input; see gestalt_Unicode.
void
glk_request_char_event (winid_t win);
Request input of a Latin-1 character or special key. A window cannot have
requests for both character and line input at the same time. Nor can it have
requests for character input of both types (Latin-1 and Unicode). It is
illegal to call glk_request_char_event() if the window already has a pending
request for either character or line input.
void
glk_request_char_event_uni (winid_t win);
Request input of a Unicode character or special key. See
glk_request_char_event().
void
glk_cancel_char_event (winid_t win);
This cancels a pending request for character input. (Either Latin-1 or
Unicode.) For convenience, it is legal to call glk_cancel_char_event() even
if there is no charcter input request on that window. Glk will ignore the
call in this case.
