class << self
# Normalizes a territory code to a symbol.
#
# 1) Converts to string.
# 2) Downcases.
# 3) Symbolizes.
#
# The downcasing is to convert ISO 3166-1 alpha-2 codes,
# used (upper-case) for territories in CLDR, to be lowercase, to be
# consistent with how territory codes are surfaced in TwitterCLDR
# methods relating to phone and postal codes.

return nil if territory_code.nil?
territory_code.to_s.downcase.gsub(/^0+/, '').to_sym
end
# Normalizes each key in the 'arg' hash or constituent hashes as
# if it were a territory code.
#
# In addition, removes entries in hashes where the key begins with a digit.
# Because of the way the twitter-cldr-rb YAML resource pipeline works,
# these three-digit codes get mangled (e.g. interpreted as octal then
# reinterpreted out in decimal), and translations for UN three-digit
# area codes cannot be trusted.
