Special Characters

Several Unicode characters are supported. They can be entered with unicode literals as 4-digit hexadecimal escape sequences.

Example characters (find the code for your character at Unicode Charts):

Code	Character	Name
u"\u03b1"	α	Alpha
u"\u03b2"	β	Beta
u"\u00c5"	Å	Ångström
u"\u00b1"	±	plus/minus
u"\u00b2"	²	superscript 2

Example 1

The alpha and beta are Unicode characters.

# if Python is configured with utf-8 default encoding (all incentive builds)
label  5/CA, u"\u03b1-Helix"
label 10/CA, u"\u03b2-Sheet"

# if Python is configured differently, explicit utf-8 encoding is necessary
label  5/CA, u"\u03b1-Helix".encode("utf-8")
label 10/CA, u"\u03b2-Sheet".encode("utf-8")

# italic
set label_font_id, 16

# make bigger
set label_size, 50

# cast shadows in ray tracing
set label_shadow_mode, 3

Example 2

Notice the Angstrom and superscript 2 characters. You can add other characters as well.

# label residue 30 with "4.1 Ang^2 +/- 0.65 Ang^2
label i. 30, "4.1" + u"\u00c5\u00b2  \u00b1 0.65 \u00c5\u00b2 "
