hello emma don't know if you are still here but I found this kinda curious,
when I input a password-string with high ANSI characters it says it is more than 72 characters
if i input
úÑF½=õF6èÆê¼¾(bõAÔÑ!ìªÒÄY\ÍvX5goFÚØÈÙ±LØ]ûzQÚï}ö¯fÓq»ÖßïxÍÁáèFu¤T:1q'®X¹ (which keepass says is 72 characters long) as my password, it returns "This value is too long. It should have 72 characters or less."
similar results are achieved when I input 71, 70 character long strings and potentially even lower
