Why does PyMuPDF print checkmarks instead of 'X' for checkboxes.

For the same PDF document, I noticed that when I fill in a checkbox using Apple Preview, or Adobe Acrobat, selected checkboxes are shown as [X]. Whereas, when I check a checkbox using PyMuPDF, the checkbox shows as [✓].

Apple Preview

Adobe Acrobat

PyMuPDF

if widget.field_type == PDF_WIDGET_TYPE_CHECKBOX:
    widget.field_value = True

Is this configurable? I have tried setting widget.text_font and widget.text_fontsize, but with no success.

My main concern is that the screen readers / scanners that read the printed form will misread the checkboxes if they are selected in this non-standardized way.

No, this behavior is based on MuPDF's appearance stream creation and cannot be changed.
