Unable to use font "CMU Serif"

[benblamey]

I am using matplotlib to create a figure as a PDF.
I get an error "TrueType font file contains a very long PostScript name" when attempting to use the font "CMU Serif" (this is the default LaTeX font)

I set up font like this:

import matplotlib
matplotlib.rcParams['font.family'] = 'serif'
matplotlib.rcParams['font.serif'] = 'CMU Serif, Times New Roman'

% Export my figure like this (it works fine with other fonts)

savefig("my_figure.pdf", dpi=600, figsize=(8, 6))

RuntimeError: TrueType font file contains a very long PostScript name

[edited by TAC to add mark up, adding tripple '`' around text makes it fontify]

Github blocks the upload of the font - but the files are available here:
http://sourceforge.net/projects/cm-unicode/

I used the font in the file: cmunrm.ttf

Might be an easy fix of making the buffer "temp" a bit longer (its currently set to 80 characters - seems to be used for the whole bag of strings for font - and hence too short)

@jkseppan @mdboom Thoughts?

[jkseppan]

Couldn't reproduce. A complete self-contained example would help. I tried using a FontProperties instance with fname='cmunrm.ttf' and got a pdf file with CMUSerif-Roman as the font.

Closing as we could not reproduce. If you have a SCCE, ping me to have this re-opened.
