(Implementation, 2.0 only) The ucnhash module is an implementation module, which provides a name to character code mapping for Unicode string literals. If this module is present, you can use N{} escapes to map Unicode character names to codes, as shown in Example 8-4.

File: ucnhash-example-1.py

# Python imports this module automatically, when it sees
# the first N{} escape
# import ucnhash

print repr(u"N{FROWN}")
print repr(u"N{SMILE}")
print repr(u"N{SKULL AND CROSSBONES}")
