Hello @chokpaisan.s where did you’ve faced with this error ? Is it occurs on our git hub sample or you’ve used our GroupDocs.Annotation .NET library on you own custom UI ?
Or is it our web application ( ?

Do you need that we to add ability to specify custom fonts to use on documents ?

Could you also please provide us a document that you’ve used, so we could test

i use Annotation webforms c# (
pls Test follow me step by step

  1. import pdf file
  2. choose tool Text field and input “Thai language” (ทดสอบ) Font Arial
  3. save
    If you have tried change font to Tahoma and save
