unicodedata2

unicodedata backport/updates. Currently supports Unicode 18.0.0.

Requires Python 3.9 or newer.

The versions of this package match Unicode versions, so unicodedata2==13.0.0 is data from Unicode 13.0.0.

Pre-compiled wheel packages are available on PyPI and can be installed via pip.

Testing

We run the tests using tox. This can be installed as usual with pip install tox, or with pip install --group dev (pip 25.1 or newer) to pick it up from pyproject.toml.

Tox and CI download the version-matched Unicode normalization data before running tests. Download failures stop the run. Before running pytest directly, run python tests/download_test_data.py once. The downloaded files are not included in source distributions or wheels.

Without any options, tox will run the tests against all of the library's target Python versions. Any missing versions will be skipped.

To run tests against a specific python version you can use the -e option followed by a tox environment name. E.g. -e py39 will run tests against Python 3.9. For more info, check tox's documentation.
