The QR code itself does not contain any currency symbols or text. It simply contains a pattern of black and white squares that can be read and decoded by a QR code reader app.

Therefore, the issue might be with the app or device used to view the code. It could be that the device or app does not have support for the currency symbol or encoding used in the QR code. This could result in displaying a different symbol or a question mark instead of the intended currency symbol.

To resolve this issue, the app or device used to view the QR code may need to be updated with the latest software or encoding standards.
