Group, This error occurs for me with Matplotlib 0.99.1, Python 2.5.4 and 2.6.2, while using the Qt4Agg backend on Windows XP.
Basically, savefig('aweomse_plot.pdf') barfs if I have some math text in there. For example: -------------------------------------------------- |C:\Documents and Settings\phobson>ipython26 -pylab |Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit (Intel)] |Type "copyright", "credits" or "license" for more information. | |IPython 0.10 -- An enhanced Interactive Python. |? -> Introduction and overview of IPython's features. |%quickref -> Quick reference. |help -> Python's own help system. |object? -> Details about 'object'. ?object also works, ?? prints more | | Welcome to pylab, a matplotlib-based Python environment. | For more information, type 'help(pylab)'.In [1]: x = arange(10) | |In [2]: y = 0.5*x**2 | |In [3]: plot(x,y,'ko') |Out[3]: [<matplotlib.lines.Line2D object at 0x039F3C10>] | |In [4]: savefig('test.png') | |In [5]: savefig('test.pdf') | |In [6]: xlabel('rSome math: $X$') |Out[6]: <matplotlib.text.Text object at 0x03A7A350> | |In [7]: savefig('test.pdf') -------------------------------------------------- Spits out a nasty error at Input Line 7. I've include it below my sig for those who might want to look at it. I don't know much about back ends, but I feel like I've neglected to install something since the last line of the TraceBack includes "ValueError: unichr() arg not in range(0x10000) (narrow Python build)". I have an update-version of MikTeX on this machine. Any thoughts? Many thanks, Paul M.
