All three platforms (if you include Gtk, Qt etc.) have special Unicode-aware APIs, and each deals with things differently. The approach I took basically leverages all the trouble the Python core guys put into to make this work cross-platform. > See the "Unicode > >> filenames" section of the link below for some of the complications. >> Linux is particularly hard to get right: >> >> http://www.amk.ca/python/howto/unicode >> > > Thanks, that's a good one. > > > you can do the following as a workaround > >> (with a performance hit from making many Python function calls): >> >> savefig(open(u"CrazyUnicodeFilename.png", "w")) >> > > thanks, I'll give that a try.

In 0.91.2, it calls the "write" method on the Python object for each block of PNG data. SVN still supports that approach (to handle arbitrary Python file-like objects), but will extract the real C file handle if it is in fact a real file.
