OpenCC

Chinese character conversion between Simplified/Traditional and regional variants. Use when Pi needs to convert Chinese text with precision and awareness of regional differences (Mainland China, Taiwan, Hong Kong, Japanese Kanji). Supports phrase-level conversion, character variants, and regional idioms. Helps generate more accurate Chinese in multilingual contexts.

OpenCC Skill for OpenClaw

Convert Chinese text with precision using OpenCC (Open Chinese Convert).

Quick Start

Basic Conversions

import opencc

# Simplified → Traditional
converter = opencc.OpenCC('s2t.json')
result = converter.convert('汉字')  # → 漢字

# Traditional → Simplified  
converter = opencc.OpenCC('t2s.json')
result = converter.convert('漢字')  # → 汉字

# Simplified → Taiwan Standard (正體)
converter = opencc.OpenCC('s2tw.json')
result = converter.convert('软件')  # → 軟體

# Simplified → Hong Kong variant (繁體)
converter = opencc.OpenCC('s2hk.json')
result = converter.convert('软件')  # → 軟件

Use Cases

When to Use OpenCC

1. Blog writing with regional awareness — Ensure blog uses consistent Taiwan/Mainland terminology
2. Content localization — Convert content for different Chinese-speaking regions
3. Character normalization — Standardize variant characters (e.g., 裏 vs 裡)
4. Multi-script content — Convert between Chinese and Japanese Kanji as needed

Region-Specific Guidance

• Mainland China: Use s2t for traditional, t2s for simplified
• Taiwan (正體): Use s2tw for precise Taiwan terminology, s2twp for common phrases
• Hong Kong: Use s2hk for Hong Kong variant
• Japan: Use t2jp for modern Japanese Kanji

CLI Usage

Use the included convert.py script:

# Command line conversion
python scripts/convert.py --source s2t "汉字转换"

# With stdin
echo "汉字转换" | python scripts/convert.py --source s2t

# Save to file
python scripts/convert.py --source s2t --input input.txt --output output.txt

Installation

# Using uv (recommended)
uv add opencc

# Or with pip
pip install opencc

API Reference

• Detailed conversion mode descriptions
• Common conversion patterns

Characteristics

• Character-level conversion: Precise character-by-character transformation
• Phrase-level conversion: Smart phrase detection for accurate multi-character terms
• Variant handling: Distinguishes between character variants (e.g., 裏/裡)
• Regional awareness: Customized rules for Mainland, Taiwan, Hong Kong, Japan
• No linguistic translation: Converts writing system only, not meaning

Limitations

• Not a translator: Converts writing systems, not languages. Cannot convert between Cantonese/Mandarin or other dialects.
• Phrase-based: Some contexts may require manual review (e.g., proper nouns, technical terms)
• Regional boundaries: Different regions have different standards; always verify output matches your target
