""" Locale support.

    The module provides low-level access to the C lib's locale APIs
    and adds high level number formatting APIs as well as a locale
    aliasing engine to complement these.

    The aliasing engine includes support for many commonly used locale
    names and maps them to values suitable for passing to the C lib's
    setlocale() function. It also includes default encodings for all
    supported locale names.

# The locale_alias table maps lowercase alias names to C locale names
# (case-sensitive). Encodings are always separated from the locale
# name using a dot ('.'); they should only be given in case the
# language name is needed to interpret the given encoding alias
# correctly (CJK codes often have this need).
#
# Note that the normalize() function which uses this tables
# removes '_' and '-' characters from the encoding part of the
# locale name before doing the lookup. This saves a lot of
# space in the table.
