Research direction

Investigate the AcroForm TextField implementation in jsPDF's source code (likely in AcroForm.js). Check if the fontName and fontStyle properties are used when rendering the form text. Compare with how doc.setFont works for regular text. The fix may involve mapping the custom font to the PDF's font dictionary and using it in the form field's appearance stream.
