#65 PyX crashes when trying to write a non-ascii character

[mmb]

Hi all,

PyX fails, when trying to write non-ascii-characters.
PyX-Version is 14.1
Python-Version is 3.4.3

A minimal example and the corresponding Traceback follow:

 # -*- coding: utf-8 -*-

from pyx import *
c = canvas.canvas()
c.text(0, 1, r"Test ä")
c.writeEPSfile("Test")

Traceback:

File "Test.py", line 7, in <module>
c.text(0, 1, r"Test ä")
File "/usr/lib/python3.4/site-packages/pyx/canvas.py", line 409, in text

While the traceback doesn't look nice (and the error in atexit is probably to be addressed), PyX is doing fine here. By default PyX encodes the text passed to TeX using the ascii encoding. You can change it by setting a proper texenc. At the same time you need to configure TeX (or better LaTeX) to accept those characters. Adding two lines to make this settings, your example will run fine:

from pyx import *
text.set(cls=text.LatexRunner, texenc='utf-8')
text.preamble(r'\usepackage[utf8]{inputenc}')
c = canvas.canvas()
c.text(0, 1, r"Test ä")
c.writeEPSfile("Test")

Not a bug, closing.
