# Encoding Fix (English)

Repairs mojibake (double/triple encoded UTF-8) caused by Windows cp1252/Latin-1
misinterpretation. Zero dependencies — Python stdlib only.

## Typical Problem

```
"ue" (U+00FC) -> UTF-8 \xc3\xbc -> read as cp1252 -> "ü"
```

## Usage

### As Library
```python
from encoding_fix import sanitize_outbound

clean = sanitize_outbound("Würge")  # -> "Wuerge"
```

### Subprocess Output
```python
from encoding_fix import sanitize_subprocess_output

text = sanitize_subprocess_output(process.stdout)
```

### CLI
```bash
python encoding_fix.py "Würge"    # Check a single string
python encoding_fix.py              # Self-test
```

## Features

- **Idempotent:** Correctly encoded text is not modified
- **Up to 3 rounds:** Repairs even triple-encoded strings
- **Subprocess decoder:** UTF-8/cp1252 fallback for process output
- **Zero dependencies:** Python stdlib only
