Subject: [PATCH 8/8] Address security hotspots and improve reliability
- Replace dynamic SQL generation with static string literals to prevent SQL injection
- Add input validation to prevent processing empty/invalid values
- Add early return optimization for strings without accents
- Remove unsafe addslashes() usage in favor of static SQL strings
These changes should resolve SonarQube security hotspots and reliability concerns.
