Saving to svg fails with use of textcomp character

[Christopher Barrington-Leigh]

The following code (under standard packages of Ubuntu 15.04)

from pylab import *
pp={'text.usetex': True,
           'text.latex.unicode': True,
           }
rcParams.update(pp)

plot(1,1)
ylabel(r'\textwon')
savefig('tmp.pdf')
print('Saved pdf')
savefig('tmp.png')
print('Saved png')
savefig('tmp.svg')
print('Saved svg')

gives output:

Saved pdf
Saved png
/usr/lib/python2.7/dist-packages/matplotlib/textpath.py:387: UserWarning: The glyph (142) of font (/usr/share/texmf/fonts/type1/public/cm-super/sfrm3583.pfb) cannot be converted with the encoding. Glyph may be wrong
  "be wrong" % (glyph, font_bunch.filename))
Saved svg

While the files pdf and png have the \textwon character properly rendered, it is missing from the svg.

Behaviour is even worse after my upgrade 16.04:

The following crashes ipython:

pp={'text.usetex': True, 'text.latex.unicode': True,}
rcParams.update(pp)
plot(1,1)
ylabel(r'\textwon')

I can confirm that this bug is affecting me too on Linux Mint 18.1 using matplotlib 2.0. Some glyphs cannot be successfully converted when saving as SVG with text.usetex set to True. Surprisingly, setting svg.fonttype from path to none does not solve this problem either. A fix would be much appreciated.

Status changed to 'Confirmed' because the bug affects multiple users.
