+=================================
+Using accented text in matplotlib
+=================================
+
+Matplotlib supports accented characters via TeX mathtext or unicode.
+
+Using mathtext, the following accents are provided: \hat, \breve, \grave, \bar,
+\acute, \tilde, \vec, \dot, \ddot.  All of them have the same syntax,
+e.g., to make an overbar you do \bar{o} or to make an o umlaut you do
+\ddot{o}.  The shortcuts are also provided, e.g.,: \"o \'e \`e \~n \.x
+\^y
