OpenCC (Open Chinese Convert) is a deterministic, dictionary-based Chinese text conversion library and CLI tool that converts between Simplified Chinese, Traditional Chinese, and regional variants (Taiwan, Hong Kong, Japan), including experimental Small Seal Script (Unicode 18.0). It is used in production by input method engines (RIME, fcitx), dictionary tools (GoldenDict), and NLP pipelines for text normalization and preprocessing. The core is a C++ library with a plugin-based segmentation system (built-in mmseg, optional jieba). Conversion is config-driven via JSON files that define normalization, segmentation, and a chain of dictionary groups with match policies (short_circuit, union). Dictionaries are compiled from text files into binary formats (marisa-trie .ocd2, legacy .ocd). The library exposes C, C++, Python (pybind11), and Node.js (N-API) APIs. A CLI tool provides conversion, inspection, ambiguity detection, and dictionary management. Data flows: text input is segmented, then each segment is looked up in a chain of dictionaries (character, phrase, regional variants). The first match is used (short_circuit) or all matches are unioned. The result is reassembled. The system supports streaming conversion with bounded memory via chunked processing. External dependencies include marisa-trie, darts-clone, rapidjson, pybind11, Google Test, and Google Benchmark; optional jieba (C++ fork) for segmentation plugin.
This repository provides Simplified Chinese language packs for WHMCS (Web Host Manager Complete Solution), a web hosting billing and automation platform. It contains PHP array files mapping English interface strings to Chinese translations for multiple versions of WHMCS (from 7.x to 9.0.4). The translations are generated using AI-assisted machine translation followed by human proofreading and optimization, as described in the accompanying documentation. The repository is actively maintained, with updates aligned to WHMCS releases, and uses the override mechanism for compatibility with newer WHMCS versions. While the repository does not contain reusable data processing components, it serves as a stable, versioned resource for deploying WHMCS in Chinese-speaking environments.
