Hi! I am using matplotlib 0.99.0 under windows xp. I tried the following: ax.text(.96,.80,r'$P \perp Q$',fontsize=18,horizontalalignment='right',verticalalignment='top',transform=ax.transAxes,color='black') and get the following error: (However, in figure labels, symbols using mathtext, such as theta seem to work fine...)

It looks like the end of the traceback -- where the actual exception is named -- is missing. Can you repost it in its entirety? Mike william ratcliff wrote: > Hi!

One might see that error if the path to the font being used contains non-ascii characters (the "basename" variable in the last frame of the stack in the stacktrace). Is that possible? We may need to implement the same workaround we use for image files for loading fonts (which is to open the file with Python and pass a file handle to C++ rather than passing a string that may contain Unicode, which is difficult to handle in cross-platform way from C/C++).

Assuming that the matplotlibrc file being read is in mpl-data, here is the relevant section: ### FONT # # font properties used by text.Text. See # http://matplotlib.sourceforge.net/api/font_manager_api.html for more # information on font properties. The 6 font properties used for font # matching are given below with their default values. # # The font.family property has five values: 'serif' (e.g. Times), # 'sans-serif' (e.g. Helvetica), 'cursive' (e.g. Zapf-Chancery), # 'fantasy' (e.g. Western), and 'monospace' (e.g. Courier). Each of # these font families has a default list of font names in decreasing # order of priority associated with them. # # The font.style property has three values: normal (or roman), italic # or oblique. The oblique style will be used for italic, if it is not # present. # # The font.variant property has two values: normal or small-caps. For # TrueType fonts, which are scalable fonts, small-caps is equivalent # to using a font size of 'smaller', or about 83% of the current font # size. # # The font.weight property has effectively 13 values: normal, bold, # bolder, lighter, 100, 200, 300, ..., 900. Normal is the same as # 400, and bold is 700. bolder and lighter are relative values with # respect to the current weight. # # The font.stretch property has 11 values: ultra-condensed, # extra-condensed, condensed, semi-condensed, normal, semi-expanded, # expanded, extra-expanded, ultra-expanded, wider, and narrower. This # property is not currently implemented. # # The font.size property is the default font size for text, given in pts. # 12pt is the standard value. # #font.family : sans-serif #font.style : normal #font.variant : normal #font.weight : medium #font.stretch : normal # note that font.size controls default text sizes. To configure # special text sizes tick labels, axes, labels, title, etc, see the rc # settings for axes and ticks. Special text sizes can be defined # relative to font.size, using the following values: xx-small, x-small, # small, medium, large, x-large, xx-large, larger, or smaller #font.size : 12.0 #font.serif : Bitstream Vera Serif, New Century Schoolbook, Century Schoolbook L, Utopia, ITC Bookman, Bookman, Nimbus Roman No9 L, Times New Roman, Times, Palatino, Charter, serif #font.sans-serif : Bitstream Vera Sans, Lucida Grande, Verdana, Geneva, Lucid, Arial, Helvetica, Avant Garde, sans-serif #font.cursive : Apple Chancery, Textile, Zapf Chancery, Sand, cursive #font.fantasy : Comic Sans MS, Chicago, Charcoal, Impact, Western, fantasy #font.monospace : Bitstream Vera Sans Mono, Andale Mono, Nimbus Mono L, Courier New, Courier, Fixed, Terminal, monospace ### TEXT # text properties used by text.Text. See # http://matplotlib.sourceforge.net/api/artist_api.html#module-matplotlib.textfor more # information on text properties #text.color : black ### LaTeX customizations. See http://www.scipy.org/Wiki/Cookbook/Matplotlib/UsingTex #text.usetex : False # use latex for all text handling. The following fonts # are supported through the usual rc parameter settings: # new century schoolbook, bookman, times, palatino, # zapf chancery, charter, serif, sans-serif, helvetica, # avant garde, courier, monospace, computer modern roman, # computer modern sans serif, computer modern typewriter # If another font is desired which can loaded using the # LaTeX \usepackage command, please inquire at the # matplotlib mailing list #text.latex.unicode : False # use "ucs" and "inputenc" LaTeX packages for handling # unicode strings. #text.latex.preamble : # IMPROPER USE OF THIS FEATURE WILL LEAD TO LATEX FAILURES # AND IS THEREFORE UNSUPPORTED. PLEASE DO NOT ASK FOR HELP # IF THIS FEATURE DOES NOT DO WHAT YOU EXPECT IT TO. # preamble is a comma separated list of LaTeX statements # that are included in the LaTeX document preamble. # An example: # text.latex.preamble : \usepackage{bm},\usepackage{euler} # The following packages are always loaded with usetex, so # beware of package collisions: color, geometry, graphicx, # type1cm, textcomp. Adobe Postscript (PSSNFS) font packages # may also be loaded, depending on your font settings #text.dvipnghack : None # some versions of dvipng don't handle alpha # channel properly. Use True to correct # and flush ~/.matplotlib/tex.cache # before testing and False to force # correction off. None will try and # guess based on your dvipng version #text.markup : 'plain' # Affects how text, such as titles and labels, are # interpreted by default. # 'plain': As plain, unformatted text # 'tex': As TeX-like text. Text between $'s will be # formatted as a TeX math expression. # This setting has no effect when text.usetex is True. # In that case, all text will be sent to TeX for # processing. # The following settings allow you to select the fonts in math mode. # They map from a TeX font name to a fontconfig font pattern. # These settings are only used if mathtext.fontset is 'custom'. # Note that this "custom" mode is unsupported and may go away in the # future. #mathtext.cal : cursive #mathtext.rm : serif #mathtext.tt : monospace #mathtext.it : serif:italic #mathtext.bf : serif:bold #mathtext.sf : sans #mathtext.fontset : cm # Should be 'cm' (Computer Modern), 'stix', # 'stixsans' or 'custom' #mathtext.fallback_to_cm : True # When True, use symbols from the Computer Modern # fonts when a symbol can not be found in one of # the custom math fonts. #mathtext.default : it # The default font to use for math. # Can be any of the LaTeX font names, including # the special name "regular" for the same font # used in regular text.

On the plus side, there is no longer an error when I apply the patch. On the downside, it generates a rather strange symbol instead of a perpendicular symbol....Let me try to quickly upgrade to 0.99.1. I did that and I seem to get the same error...

The puzzling thing is this: u'C:\\WINDOWS\\Fonts\\HTOWERTI.TTF' It's using a custom font in mathtext. Are you setting the rcParams mathtext.fontset or mathtext.default? That may the culprit, and if not, it's a bug that it's trying to use that font. Mike william ratcliff wrote: > On the plus side, there is no longer an error when I apply the patch.

Hmm... I'm a bit stumped. Can you print out the values of these from your script, i.e. put the following at the top: from matplotlib import rcParams print rcParams['mathtext.fontset'] print rcParams['mathtext.default'] Can you try deleting your fontList.cache file?

Progress:
c:\python25\lib\site-packages\matplotlib\mathtext.py:848: MathTextWarning:
Font 'rm' does not have a glyph for '\perp'
MathTextWarning)
c:\python25\lib\site-packages\matplotlib\mathtext.py:849: MathTextWarning:
Substituting with a dummy symbol.
warn("Substituting with a dummy symbol.", MathTextWarning)
----
Next, I followed your suggestion and deleted the fontlist.cache file and
that solved everything. Thanks!!!
So, that's where the dummy symbol is coming from.

That's great news -- glad we got to the bottom of it, though I'm not
sure how your system may have become wedged like that in the first
place. I should have thought of this earlier, but if it happens again,
can you send me your fontList.cache file so I can inspect it? There may
be a bug in the font lookup code there.
Cheers,
Mike
