Properly processing unicode user input is surprisingly tricky:

• Ensuring bidirectional markers are balanced properly
• Trimming whitespaces and handling esoteric unicode whitespaces well
• Normalizing unicode equivalent characters to a well-known form
• Harmonizing newlines to a single format
• … and more

With Uffff the problem is reduced to:

$good = Uffff\unicode($bad);

Read the docs to learn more.

Uffff uses direnv to set up the development environment. Run direnv allow to initialize the development environment.

To switch to a different PHP version for development or if you prefer not to use direnv, you can use nix develop to initialize the environment:

• nix develop github:loophp/nix-shell#env-php82 --impure to select PHP 8.2
• nix develop github:loophp/nix-shell#env-php83 --impure to select PHP 8.3
• nix develop github:loophp/nix-sphinx to set up sphinx to build documentation

Change the code and then run composer check to run tests, static inspection, everything and the kitchen sink. Once that succeeds, open a pull request.

Edit the documentation in docs/ and run composer docs to build the documentation. Open build/docs/html/index.html in a browser to view the HTML version.
