What is the correct way to interpret these symbols that come to me as a
string?
Part of it depends on where you're getting them from. If they are in
your source code, just define them like this:
units = u"°"
print units
°
print repr(units)
u'\xb0'
If they're coming from an external source, you have to know the
encoding they're being sent in. Then you can decode them into
unicode, like this:
units = "°"
unicode_units = units.decode('Latin-1')
print repr(unicode_units)
u'\xb0'
print unicode_units
°

Even with source code you have to know the encoding. for pre-3.x, Python
defaults to ascii encoding for source files:
test.py contains:
units = u"°"
import test
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "test.py", line 1
SyntaxError: Non-ASCII character '\xb0' in file test.py on line 1, but no
encoding declared; see http://www.python.org/peps/pep-0263.html for details
The encoding of the source file can be declared:
# coding: latin-1
units = u"°"
import test
test.units
u'\xb0'
print test.units
°
Make sure to use the correct encoding! Here the file was saved in latin-1,
but declared utf8:
# coding: utf8
units = u"°"
import test
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'utf8' codec can't decode byte 0xb0 in position 0:
unexpected code byte
