This is a bug -- but it has a fairly straightforward fix: to use 
Sphinx's "include" directive rather than roll our own as we currently 
do.  This has been fixed in SVN r7972.  plot-directive now takes an 
"encoding" option, exactly like the Sphinx include directive.  It does 
not do automatic encoding detection (meaning it ignores the "# coding: 
latin1" comments), just as the Sphinx include directive does.

I'm not sure if there's a workaround "outside" of matplotlib, other than 
to ensure the source files are encoding in pure ascii (by using unicode 
escapes in literals instead of the real characters).  But that's not a 
great workaround.

Hello,

I'm using the matplotlib Sphinx extension which automatically includes the
source
code and the figures it produces into the Sphinx document. This is a very
handy
feature whose use goes far beyond documenting matplotlib itself. (thanks for
that by the way)

However I have trouble when the python file passed to the plot directive
contains
non-ascii characters. I set up a simple example located there :
http://github.com/sbarthelemy/SphinxEncoding

running "make html" on it raises:
  Exception occurred:
    File "/usr/lib/pymodules/python2.6/sphinx/highlighting.py", line 167, in
highlight_block
      source = source.decode()
  UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 37:
ordinal not in range(128)
  The full traceback has been saved in /tmp/sphinx-err-5kW6ih.log, if you
want to report the issue to the author.

So, I've got a few questions:

- is this expected ?
- is there a workaround ?
- if not, how hard would it be to fix this problem, maybe I could help a bit
(with proper guidance).

Thank you for any help !

PS: I use sphinx 0.6.2-1 and matplotlib 0.99.0-1ubuntu1, both shipped from
ubuntu karmic

In gnuplot, I can do the following:

set format x "%.0s %cHz"

...and this will set the x-axis labels (on a semilogx style plot) to
be "10 Hz", "100 Hz", "1 kHz", "10 kHz", etc.

Is there an easy way to do this in matplotlib? I spent a while in the
matplotlib.ticker docs, but couldn't find anything.

Cheers,
Jason
