An apostrophe is inserted before an adjacent numbered a, o or e syllable, as in xi1an1 → xī'ān. Marked multisyllable words without separators are not segmented automatically.
Inside recognized syllables, use ü, v or u:, for example lü4, lv4 or lu:4. Tone 5 or 0 produces an unmarked neutral syllable. In the reverse direction, an unmarked syllable stays unmarked; no tone is guessed.
No. It changes the notation of Pinyin you supply. It does not translate, generate Pinyin from Chinese characters or validate the pronunciation of a sentence.
Unknown syllables and conflicting marks or digits stay intact with a warning. Rare syllabic m/n spellings are not supported. Converted syllables use composed Unicode characters; unrelated text and punctuation stay unchanged.
