known_number_systems_like(Cldr.Locale.locale_name(), number_system(), t()) :: {:ok, list()} | {:error, {module(), String.t()}}
Returns locale and number systems that have the same digits and separators as the supplied one.
Transliterating between locale & number systems is expensive. To avoid unncessary transliteration we look for locale and number systems that have the same digits and separators. Typically we are comparing to locale "en" and number system "latn" since this is what the number formatting routines use as placeholders.
This function is intended for use at compile time only and is used to help optimise the generation of transliteration functions.
