These can be used e.g. in plot labels (must be escaped - i.e. \u00e4):

character	output	unicode
degree	°	u00b0
alpha	α	u03b1
beta	β	u03b2
mu	µ	u00b2
omega	Ω	u03a9
squared	²	u00b3
cubed	³	u00b5
subscript number	₂	u208_ (replace with desired number)
e accent aigu	é	u00e9
e accent grave	è	u00e8
	ü	u00fc
	ä	u00e4
