/**
 * Attempts to type the given keysym by decomposing the associated character
 * into the dead key and base key pair which would be used to type that
 * character on a keyboard which lacks the necessary dedicated key. The key
 * events for the dead key and base key are sent only if the keyboard layout of
 * the given keyboard defines those keys.
 *
 * For example, the keysym for "ò" (0x00F2) would decompose into a dead grave
 * (`) and the base key "o". May it rest in peace.

 *     The guac_rdp_keyboard associated with the current RDP session.

 *
 * @return
 *     Zero if the keysym was successfully decomposed and sent to the RDP
 *     server as a pair of key events (the dead key and base key), non-zero
 *     otherwise.
