Bug summary

r"$\|$" should render as a double vertical bar, which it does with usetex or with math_fontfamily="cm", but not with the default "dejavusans" math_fontfamily.

Code for reproduction

s=r"single$|$ double$\|$"figtext(.5,.7,s);figtext(.5,.6,s,math_fontfamily="cm");figtext(.5,.5,s,usetex=True)

Actual outcome

Expected outcome

Double vertical bar in the first line too.
