Scanner scanned value incomplete in textbox

Question

Guys:
I have GS1-128 Barcode such like the pic at below:

And I will using a scanner to analysis data of this barcode.
Then I put a textbox in winform and try to scan with a scanner, but it is very strange thing happened.

In windows 10 20H2 with .net 4.8 the value of textbox is "24043112\u001d103100403\u001d37192\u001d90913";

But in windows 10 1809 with .net 4.8 the value of textbox is "240431121031004033719290913";

Then I have tried to scan this barcode in notepad++.
both of windows version was getting well which was the same value.

Finnaly, I put the value which scanned in notepad++ in textbox, the value was complete with GS code.

And I have compared the unicode configuration of windows, it was same.
So, I think .net was supported this unicode ,but there is some configuration of windows was different, then the textbox get different value.

Could any one help me analysis issue?
Thanks.
