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

Conversion Modes

Config	Source	Target	Use Case
s2t.json	Simplified	Traditional (OpenCC)	Generic traditional conversion
t2s.json	Traditional	Simplified	Generic simplified conversion
s2tw.json	Simplified	Taiwan Standard (正體)	Taiwan-specific terminology
tw2s.json	Taiwan Standard	Simplified	Taiwan to Mainland
s2hk.json	Simplified	Hong Kong (繁體)	Hong Kong variant
hk2s.json	Hong Kong	Simplified	Hong Kong to Mainland
s2twp.json	Simplified	Taiwan + idioms	Taiwan terminology + common phrases
tw2sp.json	Taiwan	Simplified + idioms	Taiwan to Mainland with idioms
t2tw.json	Traditional	Taiwan Standard	Standardize to Taiwan
t2hk.json	Traditional	Hong Kong	Standardize to Hong Kong
hk2t.json	Hong Kong	Traditional	Hong Kong to OpenCC standard

jp2t.json	Japanese	Traditional Chinese	Japanese to traditional Chinese
tw2t.json	Taiwan Standard	Traditional	Taiwan to OpenCC standard

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

See references/opencc_guide.md for:

• Detailed conversion mode descriptions
• Common conversion patterns
• Performance considerations
• Troubleshooting

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
