Special Character

[yunotruong-novobi]

Hi everyone, I facing an issue when updating a widget value by a string containing a special character, It still updates on the field_value, but does not render on the pdf when I open it by browser or any view pdf file tool

here is my code

doc =  fitz.open("example.pdf")
page = doc.load_page(0)
widgets = list(page.widgets())
widgets[0].field_value = "text contain special chracter †"
widgets[0].update()
doc.save("new.pdf")

Any suggestions for this case? thanks

PDF form fields in (Py-) MuPDF only support characters available in the Base-14 fonts, i.e. Times-Roman, Helvetica and Courier.
For checkboxes, specifying ZapfDingbats is also supported.

I am trying to insert few words which has characters like ě, ř, etc. that are not getting rendered in widget form field. How can I make it visible/rendered? Is it possible?

[JorjMcKie]

There is no way to have that. This is a consequence of currently being restricted to Base-14 fonts.

Is there any plan to support it? This restricts content from languages such as czech which has such characters and not able to display/render correctly.
However, when form field is clicked, it is visible/rendered and once pdf is saved then it remains visible/rendered. So, after interaction it might be recreating appearance.

Supporting user-supplied fonts is in our plans, but there is no fixed date yet.
