How this Pinyin converter works

Characters and context

The converter uses a versioned Mandarin pronunciation dictionary instead of treating every character in isolation. Phrase context helps with common polyphonic characters, such as 行 in 银行. Proper names and unusual senses can still need correction by a fluent reader.

Traditional and Simplified

Both character forms are accepted directly and the displayed source is never rewritten. For phrase lookup, Traditional text can use an internal Simplified dictionary form while protected lexical exceptions retain their Traditional form. Ambiguous variants can still require review.

Tones and spelling

Tone-mark output follows ordinary Hanyu Pinyin diacritics. Number output places 1–4 after a syllable; neutral tone may be left unnumbered. No-tone output removes tonal marks but keeps ü because it is a Pinyin vowel, not a tone mark.

Word boundaries

When grouping is enabled, Unicode ICU proposes Chinese word boundaries and syllables inside each detected word are joined. Chinese normally has no spaces between words, so names, compounds, and recently coined terms may be segmented differently from your intended reading.
