perhaps try printing the string fh at line 42 of
gluon/contrib/fpdf/fpdf.py ? maybe that will shed some light....
do you know if the path to the font you are adding in your controller is
correct for GAE? i don't remember off the top of my head the default
file path on GAE.

I think, the file is ok, for pdf/pyfpdf (as I said, it works good on
devservers). But maybe it is, in some way wrong for GAE... I'm confused.
But thanks for suggestion.

after a quick moment of asking google i saw the suggestions that your
error indicates something wrong with the pickled item....which i think in
this case is the font file. is your font file in the right format to be
loaded by fpdf? (i have no familiarity with this error or fpdf so i'm just
throwing out suggestions).
good luck!

Hello!
I'm writing an app, which results with pdf file with some text with
unicode characters. On local GAE it works good, but after deploy it can't
import crash after add_font() (pyfpdf).
The code is:
# -*- coding: utf-8 -*-
def fun1():
from gluon.contrib.pyfpdf import FPDF, HTMLMixin
class MyFPDF(FPDF, HTMLMixin):
pass
pdf =MyFPDF()
pdf.add_font('DejaVu', '', 'DejaVuSansCondensed.ttf', uni=True)
pdf.add_page()
pdf.set_font('DejaVu','',16)
pdf.write(10,'testąśł')
response.headers['Content-Type']='application/pdf'
return pdf.output(dest='S')
The font files (with a file *DejaVuSansCondensed.pkl* generated after
first run on web2py server...) is in /gluon/contrib/fpdf/font. I
didn't add anything to routers.py (I'm using Pattern-based system) also
app.yaml is not changed.
As I said on local (both web2py and gae) it works well. After deploy
only something like this works:
pdf =MyFPDF()
pdf.add_page()
pdf.set_font('Arial','',16)
pdf.write(10,'testąśł')
But without "unusual" characters...
The best solution would be to add my font files (like DejaVu), but
basically I need unicode characters in any font... maybe some
"half-solution" to use "generic GAE unicode" fonts... if it exist something
like this...
