[PB 6.10 beta 2] PdfVectorOutput() and CJK characters

Posted: Sun Jan 14, 2024 1:20 pm

In the code below, Chinese, Japanese, and Korean characters are not displayed correctly. (Viewed in MS Edge browser and SumatraPDF.)
They all appear as squares, as if they don't have fonts.

Code: Select all

LoadFont(0, "Arial", 20)

If StartVectorDrawing(PdfVectorOutput("z:\test.pdf", 595, 842))
  VectorFont(FontID(0), 25)
  MovePathCursor(20, 20)
  DrawVectorText("한글, ひらがな, カタカナ, 简体中文")
  StopVectorDrawing()
EndIf

Using certain fonts causes a "Division by zero" error on Windows 10 Korean.
However, on English Windows, it shows the same result as the above code without any errors.

Code: Select all

;"Division by zero" error in all of the fonts below.
Debug LoadFont(0, "MS Sans Serif", 20)
;Debug LoadFont(0, "맑은고딕", 20)
;Debug LoadFont(0, "굴림", 20)

If StartVectorDrawing(PdfVectorOutput("z:\test.pdf", 595, 842))
  ;Debug FontID(0)
  VectorFont(FontID(0), 25)
  MovePathCursor(20, 20)
  DrawVectorText("한글, ひらがな, カタカナ, 简体中文")    ; Division by zero.
  StopVectorDrawing()
EndIf
Some fonts generate a very small empty file(705 bytes) with no errors. This issue also does not occur on English Windows.
(There is some binary content in the PDF file, but when the document is opened in Edge browser or something, no characters display.)

Code: Select all

Debug LoadFont(0, "굴림체", 20)
;Debug LoadFont(0, "돋움체", 20)

If StartVectorDrawing(PdfVectorOutput("z:\test.pdf", 595, 842))
  ;Debug FontID(0)
  VectorFont(FontID(0), 25)
  MovePathCursor(20, 20)
  DrawVectorText("한글, ひらがな, カタカナ, 简体中文")
  StopVectorDrawing()
EndIf

Only Incscape and LibreOffice Draw can handle the file correctly:
