Bug report

Bug summary

Text in PDF files created with the rcParams["pdf.fonttype"] = 42 setting does not have any kerning. This can lead to text overflowing the legend box.

Code for reproduction

import matplotlib.pyplot as plt
from matplotlib import rcParams

rcParams["pdf.fonttype"] = 42

plt.plot([0, 1], [0, 1], label="Hello AVATAVATAVATAVATAVATAVAT")
plt.legend()

plt.savefig("kern42.pdf")

Actual outcome

kern42.pdf

Expected outcome

kern42.pdf
