Transliterate Cyrillic text into Latin using a named standard
Transliterate Cyrillic text into Latin using a named standard: ISO 9:1995 (one-to-one, with diacritics) or the BGN/PCGN Russian system. Returns the transliteration, the detected source script, the standard actually applied, the fraction of non-ASCII characters that were mapped, and any characters passed through untouched. Other scripts are not supported yet and are rejected with UNSUPPORTED_VALUE.
