Could we consider consolidating these tests with the unicode-emoji.spec.ts file? Both files test Unicode emoji handling, and unicode-emoji.spec.ts already covers the issue comprehensively. Having them in one file would reduce duplication and make the test suite easier to maintain.

The comment mentions expecting it to work, but could we add a more specific assertion? For example, we could verify that the similarity score is exactly 100% to prove the normalization isn't affecting emoji matching. This would make the test's intent clearer.

Great comprehensive test coverage! Have you considered adding edge cases like:
- Emoji at the very start or end of a file
- Files containing only emoji characters
- Zero-width joiners and emoji sequences (like 👨👩👧👦)
These edge cases could help ensure robustness.

Excellent test for international characters beyond emoji! This ensures the fix works for all Unicode, not just emoji. 🌍
