I'm working on a PDF generator on the Django back-end. I use reportlab. It seems to work, but the encoding is not correct. When I use diacritic characters, it gets the wrong characters/signs.
The problem is very similar to: Django - pdf response has wrong encoding - xhtml2pdf
But I use reportlab, which allows font adding. I registered in reportlab the font that supports Polish diacritics: "Aleo".
pdfmetrics.registerFont(TTFont('Aleo', './resources/fonts/Aleo/Aleo-Light.ttf'))
pdfmetrics.registerFont(TTFont('AleoBd', './resources/fonts/Aleo/Aleo-Bold.ttf'))
pdfmetrics.registerFont(TTFont('AleoIt', './resources/fonts/Aleo/Aleo-Italic.ttf'))
pdfmetrics.registerFont(TTFont('AleoBI', './resources/fonts/Aleo/Aleo-BoldItalic.ttf'))
registerFontFamily('Aleo', normal='Aleo', bold='AleoBd', italic='AleoIt', boldItalic='AleoBI')
Example outputting pdf in djagno:
file_response = Album.pdf_generator(request.user, request.data.get('album_id'))
# Make copy to save local pdf file and send via django
binary_copy = deepcopy(file_response)
with open('test.pdf', 'wb') as f:
f.write(binary_copy.read())
content_type = {'pdf': 'application/pdf'}
response = HttpResponse(file_response, content_type=content_type)
response['Content-Disposition'] = 'attachment; filename=moja_nazwa.pdf'
# response = FileResponse(file_response, as_attachment=True, filename='hello.pdf')
return response
Example two files generate from the same bytesIO:
A. Local file B. Shared FileResponse or HttpResponse file:
What's strange is if I use the "open with" option after clicking on the link "download" in swagger and I choose some other program, e.g. "wps pdf" I will get other characters in generated pdf..
Opened pdf directly from link from swagger using wps pdf:
