## What it is
A Java library for converting Chinese characters to pinyin romanization, republished from SourceForge to Maven Central. It adds polyphonic character (多音字) recognition with a built-in dictionary of ~10,000 words and support for user-supplied external dictionaries.

## Use cases
- convert chinese characters to pinyin in java
- get pinyin with tone marks from hanzi
- handle polyphonic chinese characters correctly
- sort or index chinese text alphabetically by pinyin
- build a chinese search or autocomplete feature with pinyin matching
- customize pinyin readings with an external dictionary

## When to choose
- you need a lightweight, pure-Java pinyin conversion library on the JVM
- you need polyphonic character support and want to supply your own correction dictionary
- you want a dependency available directly from Maven Central

## When to avoid
- you need pinyin conversion outside the Java/JVM ecosystem
- you need active development or modern features - the project is a maintained copy of an older library
- you need a license-guaranteed dependency - no license is specified in the repository

## Facets
- artifact type: library
- maturity: maintenance
- function: nlp, parser, internationalization
- domain: developer-tools
- platform: jvm
- tags: pinyin, chinese, chinese-characters, transliteration, multi-pinyin, maven-central, natural-language-processing, localization
