`sutton-signwriting-core` is a Python library that supports general processing of SignWriting text

This library supports both Formal SignWriting in ASCII (FSW) and SignWriting in Unicode (SWU) character sets, , along with the associated query languages and style string.  See [draft-slevinski-formal-signwriting](https://www.ietf.org/archive/id/draft-slevinski-formal-signwriting-10.html) for detailed specification.

## Usage

```python
from sutton_signwriting_core import (
    fsw_is_type, fsw_parse_symbol,
    fsw_to_coord, key_to_id
)

# FSW is type
fsw_is_type('S10000', 'hand')
True

# FSW parse symbol
fsw_parse_symbol('S10000500x500-C')
{'symbol': 'S10000', 'coord': [500, 500], 'style': '-C'}

# FSW to coord
fsw_to_coord('500x500')
[500, 500]

# FSW symbol key to 16-bit ID
key_to_id('S10000')
1
```

All functions are **fully typed**, **validated**, and **documented** with Python-style docstrings (Google format). Run `help(swu_to_fsw)` for details.
