Convert Chinese (Hanzi) text to pinyin romanization. Choose tone marks (symbol, e.g. hàn yǔ), numbered tones (han4 yu3), or no tones. Auto-segments words and returns the full pinyin string plus a per-syllable array. Deterministic, keyless — useful for transliteration, pronunciation, search indexing, and TTS prep.
