The ucnhash module

(Implementation, 2.0 only) This 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.

In Python 2.1, the functionality of this module was moved to the unicodedata module.

# 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}")
