- Fixed UTF-8 encoding test (ENC-01) to accept multiple encoding declarations - Fixed UTF-16 encoding test (ENC-02) by rewriting with correct API usage - Fixed ISO-8859-1 encoding test (ENC-03) with proper address fields and methods - All three encoding tests now pass successfully - Updated edge-cases tests (EDGE-02 through EDGE-07) with new test structure
