def self.parse(number)
  return number unless number.is_a?(String)

  # I18n.t('number.currency.format.delimiter') could be useful here, but is
  # unnecessary as it is stripped by the non_number_characters gsub.
  separator = I18n.t(:'number.currency.format.separator')
  non_number_characters = /[^0-9\-#{separator}]/

  # strip everything else first
  number = number.gsub(non_number_characters, '')

  # then replace the locale-specific decimal separator with the standard separator if necessary
  number = number.gsub(separator, '.') unless separator == '.'

  # Handle empty string for ruby 2.4 compatibility
