10.6.2.1306 EKEY>CHAR e-key-to-char FACILITY EXT
( x -- x false | char true )
If the keyboard event x corresponds to a character in the implementation-defined character set, return that character and true. Otherwise return x and false.
See:
Rationale:
EKEY>CHAR translates a keyboard event into the
corresponding member of the character set, if such a
correspondence exists for that event.
It is possible that several different keyboard events may correspond to the same character, and other keyboard events may correspond to no character.
