Character Escape Codes

Escape codes can be inserted into character input to the plotting routines in order to change the formatting of the text. The supported codes are listed below:

#u: move up to the superscript position (ended with #d)
#d: move down to subscript position (ended with #u)
#b: backspace (to allow overprinting)
##: number symbol
#+: toggle overline mode
#-: toggle underline mode
#gx: Greek letter corresponding to Roman letter x (see below)
#fn: switch to normal (sans-serif) font
#fr: switch to Roman (serif) font
#fi: switch to italic font
#fs: switch to script font

When greek letters are inserted using the code '#gx', the replacements are made according to the following rules:

= ROMAN =	= GREEK =	= roman =	= greek =
A	Α	a	α
B	Β	b	β
G	Γ	g	γ
D	Δ	d	δ
E	Ε	e	ε
Z	Ζ	z	ζ
Y	Η	y	η
H	Θ	h	θ
I	Ι	i	ι
K	Κ	k	κ
L	Λ	l	λ
M	Μ	m	μ
N	Ν	n	ν
C	Ξ	c	ξ
O	Ο	o	ο
P	Π	p	π
R	Ρ	r	ρ
S	Σ	s	σ
T	Τ	t	τ
U	Υ	u	υ
F	Φ	f	φ
X	Χ	x	χ
Q	Ψ	q	ψ
W	Ω	w	ω

One obvious application of escape codes is the formatting of axis labels, where symbols are usually italic to match their usage in the text of the document. Eg:

:::fortran
call labels('#fix#fn','#fiy#fn','#fiy=f#d0#u(x)#fn')
