You have three options then:
1-) Figure out how legend handles symbol drawing.
2-) Use latex / mathtext to represent symbols.
3-) Install a font and more intuitively insert a sqaure box into your string.
For me, as long as the expression that is drawn on screen is not
complicated, I am very happy using the unicode text approach.

I personally think that this is reasonable, as it guarantees a size
value to come from somewhere. However, I am concerned about
fontManager being None. If it isn't a bug for it to be None at this
point, then I have to wonder where-else in the code needs a check for
None? If it is a bug, then what should it be when USE_FONTCONFIG is
true?
Good catch Daniel.

Hello - I am using python 2.6, numpy-1.3.0-win32-
superpack-python2.6, scipy-0.7.1-win32-superpack-python2.6,

Thank you.

If USE_FONTCONFIG is turned on, the function
FontProperties.get_size_in_points will sometimes fail, because it is wanting
to use "fontManager", which is still 'None' if USE_FONTCONFIG is on. I'm
not sure if it's the proper way to fix it, but here is a small patch that
works (meaning that at least the code doesn't die; I can't vouch for much
else):
ORIGINAL:
 def get_size_in_points(self):
 if self._size is not None:
 try:
 return float(self._size)
 except ValueError:
 pass
 default_size = fontManager.get_default_size()
 return default_size * font_scalings.get(self._size)
NEW:
 def get_size_in_points(self):
 if self._size is not None:
 try:

 return default_size * font_scalings.get(self._size)

i get matplotlib from Sourceforge ,it's matplotlib-1.0.0.win32-py2.6.exe
OS:Win7
ActivePython-2.6.6.15-win32-x86.msi
here is the code:
# -*- coding: utf-8 -*-
import matplotlib.pyplot as plt
plt.figure(figsize=(8,4))
a = plt.text(0.05, 0.05, u"Default Font缺省字体조선어にほんごภาษาไทย")#multi language
,some cann't display
plt.text(0.05, 0.45, u"Microsoft YaHei微软雅黑", fontproperties='Microsoft
YaHei')#Chinese OK
plt.text(0.05, 0.25, u"LilyUPCภาษาไทย", fontproperties='LilyUPC')#Tai OK
plt.xlabel(u"xlabelにほんご",fontproperties='STXihei')#Japanese ,OK
plt.ylabel(u"ylabel조선어",fontproperties='Malgun Gothic')#Korea,OK
plt.show()
C:\Python26\Lib\site-packages\matplotlib\mpl-data\matplotlibrc:
font.family : sans-serif font.sans-serif : Microsoft YaHei,Malgun
Gothic,LilyUPC,FangSong,YouYuan,SimHei,STKaiti,STSong,SimSun-ExtB,Webdings,Bitstream
Vera Sans, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant
Garde, sans-serif
it seems if a default font doesn't have all char's in the "Default
Font缺省字体조선어にほんごภาษาไทย" string,it won't display correctly.
