This service defines a character from UCS.
Notes
Any module providing UCS character definitions should check to see if it can provide an 8×8 definition for the specified UCS character. If it can, it should claim the service call and define the character using VDU 23, otherwise all registers should be preserved.
This call is intended as an interim measure until the kernel supports large character sets. The International module provides several hundred character definitions – this call provides access to them.
