Use This service returns an UCS conversion table for a given alphabet number. h4. Notes Any module providing additional alphabets should check to see if it can provide a conversion table for the given alphabet number. If it can, it should claim the service and return a pointer to the table in R4, otherwise return with all register preserved. The table has 256 32-bit entries, one for each character, giving the equivalent UCS code. If a character is not defined in the alphabet, its entry should contain &FFFFFFFF (not a valid UCS character). Characters 0-31 and 127 are control codes in RISC OS - their entries in the tables of all alphabets should be 0-31 and 127 to guarantee a sensible translation to UTF8. It is nonsensical to issue this service call for alphabet UTF8 (111). No module should claim such a call. h4. See also * [[Alphabet Numbers]] * [[Service Calls]] * [[Service_International]]
