Most platforms use special fonts to generate the text on bills.

Currently, PictextEdit has implemented separate recognition of payment symbols such as "+" and "-". These symbols cannot be entered using a mobile phone or computer keyboard; the symbols from the original image must be retained and should not be edited.

The numbers related to payments need to match the corresponding font.  Since different platforms use different fonts to display payment-related numbers, PictextEdit will provide updates for these fonts in future versions.
