   I think this can be done by changing this line to:

   return r'$\mathdefault{%s}$' % (s + self.symbol)

   when text.usetex is True.

   I would also like to have PercentFormatter to support mathtext.

   Currently, there are font errors when using cmr10 font with negative percents.

   from matplotlib import pyplot as plt
   import matplotlib.ticker as mtick
   
   plt.rcParams["axes.formatter.use_mathtext"] = True
   plt.rcParams["mathtext.fontset"] = "cm"
   plt.rcParams["font.serif"] = "cmr10"
   plt.rcParams["font.family"] = "serif"
   
   plt.plot([1, 2, 3], [-1, 0, 1])
   plt.gca().yaxis.set_major_formatter(mtick.PercentFormatter())

   

   The default `ScalarFormatter` produces correct results.
