The following code fails at set_ylabel:
import matplotlib.pyplot as plt
with plt.style.context({'text.usetex': True}):
(fig, ax) = plt.subplots()
ax.set_xlabel("€")
ax.set_ylabel("Δ")
plt.show()It works with $\Delta$ instead of Δ and it works if I unset text.usetex.
The generated tex is this:
\documentclass{article}
\newcommand{\mathdefault}[1]{#1}
\usepackage{type1cm}
\usepackage{type1ec}
\usepackage{type1ec}
\usepackage{type1ec}
\usepackage[utf8]{inputenc}
\DeclareUnicodeCharacter{2212}{\ensuremath{-}}
\usepackage[papersize=72in, margin=1in]{geometry}
\makeatletter\@ifpackageloaded{textcomp}{}{\usepackage{textcomp}}\makeatother
\pagestyle{empty}
\begin{document}
% The empty hbox ensures that a page is printed even for empty inputs, except
% when using psfrag which gets confused by it.
\fontsize{10.000000}{12.500000}%
\ifdefined\psfrag\else\hbox{}\fi%
{\sffamily Δ}
\end{document}and it compiles fine with pdflatex if I replace \usepackage[utf8]{inputenc} by \usepackage[utf8x]{inputenc}. Otherwise the error is the same:
! Package inputenc Error: Unicode character Δ (U+0394)
(inputenc) not set up for use with LaTeX.
I think this is on the side of unexpected behavior.
Versions: Python 3.8.5 and matplotlib==3.4.1.
