TRTT is not in any way Unicode-dependent.  It is table-driven, does
what it is told to do.  The only requirement is that both source and
target character sets be DBCSs.  The TRTE (translate and Test
Extended) instruction is also 1) Unicode-independent and 2) processes
either SBCSs or DBCSs parametrically.   Halfword alignment is
irrelevant in all of these cases. SBCS, DBCS, or MBCS.   (A
character-set element must of course begin on some byte boundary, but
this 'restriction' is not really an interesting one.)
