thank you for your reply.
Changing the collation order and CTYPE did not change the behavior.

Hi,
I think this has something to do with collation and ctype. As I see you have it set to “C” for all your databases (even if I don’t understand your titles 😊).

Hi,
In the Length () function, it will be 2 characters where you want it to be 1 character.
Is it possible to respond by changing the settings such as changing the collation setting like SQL Server?Also, if you understand how to deal with it (eg, create your own function), it would be helpful if you could provide as much information as you can.
Try char_length(text) instead.
