2.Analysis of Issue：
Step 1: confirm the firmware version first. Only firmware of 0402 and above can scan Vietnamese. The customer uses the latest version gl-0408, which supports scanning Vietnamese.
Step 2: confirm whether have started Vietnamese scanning function.
Step 3: confirm whether have opened the Vietnamese keyboard.
Step 4: find out the possible causes. Because the Numberlock key is pressed, there will be error codes. In the on state, the scanning will reproduce the problems.
Because the Bluetooth scanning scanner is in the ALT + numeric keypad mode, there is a NumLock pressing action on the scanner. Therefore, if the NUMBERLOCK key is pressed (on), it is equivalent to popping up this key (off), and there is a problem. In the USB HID mode when the USB is connected, the scanner can detect whether the NUMBERLOCK key has been pressed. If it has been pressed, the scanner will not scan.
