Hello,
For some reason, my matplotlib isn't able to print percent signs ('%')
properly:
[1] inspiron:~/tmp# cat mplbug.py
import matplotlib
import matplotlib.pyplot as plt
import numpy as np
print matplotlib.__version__
plt.plot(np.arange(10), np.arange(10)**2)
plt.xlabel('Percent [%]')
plt.savefig('mplbug.pdf')
[0] inspiron:~/tmp# python mplbug.py
1.1.1rc2
I have attached the resulting PDF. For some reason, the slash in the
percent sign becomes a triangle that partially covers the upper left
circle.
Known bug? Any workarounds that don't require upgrading (I'd like to
stick with the Debian package)?
Thanks,
-Nikolaus

confirmed for pdf and eps figures. For jpg and png, as well as the
matplotlib window with TkAgg the percentage looks fine.
matplotlib version: 1.1.1 shipped with kubuntu 12.10

On Windows it works just fine. Just a wild guess, can you try to make
it a raw string?
plt.xlabel(r'Percent [%]')

I'm using the AGG backend and saving to a png file without any
problems, but I'm using the current git master branch. I'll try to see
if I can recreate on 1.1.1rc2. Watch this space.

No dice. I still can't recreate your problem on OS X 10.7.4 with
matplotlib version 1.1.1-rc2.
What are your font/tex specifications in the matplotlib.rcParams dictionary?

For me the problem occurs with PDF files, not PNG files. Or was that
just a typo?
Font specifications are all default.
# python -c 'import matplotlib; import pprint;
# pprint.pprint(matplotlib.rcParams)' | egrep 'tex'
'legend.handletextpad': 0.8,
'mathtext.bf': 'serif:bold',
'mathtext.cal': 'cursive',
'mathtext.default': 'it',
'mathtext.fallback_to_cm': True,
'mathtext.fontset': 'cm',
'mathtext.it': 'serif:italic',

I think I know why this is happening. Iirc, we recently took on a patch to
allow string formatting for labels. For most cases, it shouldn't effect
anybody, but if there is a lonely percent sign, I would imagine it could
cause issues. As a test, try a double percent sign '%%'. If that works,
the my theory might be right.
In addition, I think it is only in master, not v1.2.x.

Nope, using '%%' just results in two corrupted signs in the PDF.

It's a known bug, fixed since 1.1.1. https://github.com/matplotlib/matplotlib/issues/1211 BTW: If you're running the Debian package, how come the version is a release candidate?

Indeed. Luckily 1.2.0~rc2-1 is in experimental, and upgrading fixed the
problem. Thanks!
Now the only question that remains is: why doesn't github find this
issue when I search for '%'?

Not sure what you mean, why shouldn't it?

Indeed - we should file a bug with github. I was able to find it
because I knew the bug had to do with ttconv -- but there's no reason a
user should have to know that.

I had just forgotten that Debian went with a release candidate --
ideally it would have been a final release, but the schedule didn't work
out that way.
