""" 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.

### Database
#
# The following data was extracted from the locale.alias file which
# comes with X11 and then hand edited removing the explicit encoding
# definitions and adding some more aliases. The file is usually
# available as /usr/lib/X11/locale/locale.alias.
#

#
# The local_encoding_alias table maps lowercase encoding alias names
# to C locale encoding names (case-sensitive). Note that normalize()
# first looks up the encoding in the encodings.aliases dictionary and
# then applies this mapping to find the correct C lib name for the
# encoding.

# 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.
