Hi @Lorenzo Scalese 
I guess you are looking for class(%Utility).FormatString()

USER>set lb=$lb(1,"Lorenzo",2023,"RCC"_$c(13,10))
USER>write lb
      LorenzoçRCC
 
USER>zzdump lb
0000: 03 04 01 09 01 4C 6F 72 65 6E 7A 6F 04 04 E7 07         .....Lorenzo..ç.
0010: 07 01 52 43 43 0D 0A                                    ..RCC..
;;;;;  this is it
USER>set viewlb=##class(%Utility).FormatString(lb)
 
USER>write viewlb
$lb(1,"Lorenzo",2023,"RCC"_$c(13,10))
USER>zwrite viewlb
viewlb="$lb(1,""Lorenzo"",2023,""RCC""_$c(13,10))"

Your transformation produces  a YYYY-MM-DD HH:mm:SS string
in contradiction 
Property DOB As %Date;   expects an Integer similar to +$h 
The error is reported during Validation before %Save() of  your record

  • either you change  Property DOB As %String;
  • or use '$zdateh(source.DOB,7,,,,,,,,"")'   then ##class(%Date).IsValid(...)  is happy

Hi @Vivian Lee !
I think you had no chance to see the problem in docs
You mentioned 
a custom class that extends %Text.English
this might be the cause of your problem.
The class is not visible in normal class reference (don't ask me why) 

Default %Text.English has a Parameter  NOISEWORDS100 =
"the of and a to in is you that it he for was on are as with his they at be this from I have or by one had not but what all were when we there can an your which their said if do will each about how up out them then she many some so these would other into has more her two like him see time could no make than first been its who now my made over did down only way find use may long little very after called just where most know get through back";

So you might be affected by these NOISEWORDS.
I failed to find any useful public documentation on this parameter and also %Text.Text is not too useful
