Vuto ndilakuti zilembo zina za Unicode, mukamagwiritsa ntchito zilembo zazing'ono kapena zazikulu, zimamasuliridwa kukhala zilembo zofananira (pamene zilembo zingapo zimamasuliridwa kukhala munthu m'modzi - mwachitsanzo, zilembo zaku Turkey "ı" ndi "i" " akasinthidwa kukhala zilembo zazikulu amasinthidwa kukhala "I").

Musanayang'ane magawo olowera muzinthu zina ndi mapulogalamu, zomwe zimaperekedwa ndi ogwiritsa ntchito zimasinthidwa kukhala zilembo zazikulu kapena zochepa kenako ndikufufuzidwa mu database.

Adilesi idapambana mayeso chifukwa idasinthidwa kukhala zilembo zazikulu ndikufanana ndi adilesi yoyambirira ([imelo ndiotetezedwa] ), koma potumiza kalatayo idasinthidwa momwe ilili ndipo nambala yobwezeretsa idatumizidwa ku adilesi yabodza (m.ı[imelo ndiotetezedwa]).
