Text Encoding Detector

Automatically detect the character encoding of text files.

Features

• Support common Chinese encodings (UTF-8, GBK, GB2312)
• Detect BOM (Byte Order Mark) markers
• Report file size along with encoding
• Pure Python, no external dependencies

Supported Encodings

• UTF-8 (with or without BOM)
• UTF-16 LE/BE
• GBK / GB2312
• Latin-1 / ISO-8859-1
• Unknown (when detection fails)

Usage

text

python3 scripts/encoding_detector.py --file document.txt

Example Output

json

{
  "file": "document.txt",
  "encoding": "UTF-8",
  "size_bytes": 15234
}

Use Cases

• Fix garbled text files
• Batch convert files between encodings
• Verify file encoding before processing

Notes

Detection tries UTF-8 first, then GBK. If both fail, returns "UNKNOWN".
