Implements #7233 by using Jinja templates to auto-generate FFI code for 69 binary Unicode properties.

Changes

  • Added Jinja template (properties_sets.rs.jinja) for binary properties
  • Updated codegen script to generate binary property functions
  • Auto-generated FFI code for 69 binary properties

Implementation

Follows the same pattern as PR #7366 (enumerated properties). The template generates three functions for each binary property:

  • {property}_for_char() - Check property for a single character
  • create_{property}() - Create property set with compiled data
  • create_{property}_with_provider() - Create with custom provider

Testing

  • Ran cargo run -p codegen successfully
  • All generated code follows ICU4X FFI conventions
  • Ready for review

Fixes #7233

- Add Jinja template for properties_sets.rs
- Update codegen script for 69 binary properties
- Generate properties_sets.rs from template

Fixes unicode-org#7233

@Manishearth @sffc ,I've created a clean PR with only the core changes for #7233:

Update: I've made the following changes based on CI feedback:

✅ Regenerated Diplomat bindings (now 10 files changed instead of 3)
✅ Fixed template compilation error (changed properties to binary_props in the Jinja template)
✅ Code now compiles successfully locally

None should change.

✅ Fixed template compilation error (changed properties to binary_props in the Jinja template)

Still doesn't work.
