I am from China, and I have configured the form with Chinese fonts. How should I fill it?

I have tried using api.FillForm to populate it and have set up local fonts through api.InstallFonts. However, I have noticed that regardless of how I change the font in the PDF form, the font read by pdfcpu is always 'SimSun,' which corresponds to the GBK-EUC-H encoding.

this is interesting.
Can you share a simple example form and the corresponding fill.json and point me to the font you would like to use.

Then I can reproduce, analyze and fix this which I am pretty sure is a bug.

Thank you for using pdfcpu 💚

I'm sorry for keeping you waiting for so long.

I have uploaded my sample to GitHub, which includes the incorrect methods I've been using, along with the corresponding PDF and fonts. I've also included a successful example using the pdfcpu test. Please help me identify where the issue is.

Thank you once again for your assistance.

Hello!

This sample form was created especially to be filled using UnifontMedium:

7: was compressed 52[7] generation=0 types.Dict type=Font subType=Type0
<<
	<BaseFont, UnifontMedium>
	<DescendantFonts, [(44 0 R)]>
	<Encoding, UniGB-UTF16-H>
	<Name, UnifontMedium>
	<Subtype, Type0>
	<Type, Font>
>>

if you want to fill this form using pdfcpu you have to have UnifontMedium installed as a pdfcpu user font.
Right now there is no other way.

What we need is a way to specify an alternative fill font during filling and in the fill.json.
This part is still missing :(

Do you think you can provide me with a simple, genuine chinese PDF form.
Maybe you can also point me to 2 different popular chinese fonts used for PDF form filling.
And then you fill this test form once with font A and then with font B and send me the resulting 2 PDFs.
Providing support for this issue will be much easier.
Thank you.
