Hello, it is not a matter of western or non-western. the test for length=0 is only necessary if you can reasonable expect string that collates to "".
c.f. $test:=""=Char(0) $test:=""=Char(1) //both is true otherwise you can continue to use ="" for queries and string in general. 2018/02/06 0:31、webmaster namethatplant.net<http://namethatplant.net> via 4D_Tech <4d_tech@lists.4d.com<mailto:4d_tech@lists.4d.com>> のメール： QUESTION: In versions 12+, in unicode mode, if the field contains only routine Western characters, is it okay to continue to use QUERY([Table];[Table]Field="") and only if the field may contain nonWestern characters, use QUERY SELECTION BY FORMULA([Table];Length([Table]Field)=0) ??? ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
