흔히 이렇게 알고 있다

CodePage.encode and CodePage.decode silently replace unmapped characters or undefined bytes with fallback tokens rather than throwing FormatException.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• CodePage.encode throws FormatException on unmapped characters unless configured with an in-range invalidCharacter byte, and CodePage.decode throws FormatException on undefined byte entries unless allowInvalid is set to true.
• latin2.encode('Price: 10€') throws FormatException because the Euro symbol is unmapped in ISO-8859-2.
• latin2.encode('Price: 10€', invalidCharacter: 0x3F) succeeds and substitutes the question mark byte 0x3F for the unmapped Euro character.
• latin2.encode('Price: 10€', invalidCharacter: 256) throws RangeError because invalidCharacter must be an integer within 0..255.
• latin2.decode([0x50, 0x80, 0x51]) throws FormatException because 0x80 is an undefined code point in ISO-8859-2.
• latin2.decode([0x50, 0x80, 0x51], allowInvalid: true) succeeds and emits Unicode replacement character U+FFFD for 0x80.
• latin2.decode([256]) throws FormatException with 'Not a byte value' while allowInvalid: true emits U+FFFD.
• CodePage('custom', 'ABC') throws ArgumentError because CodePage table definitions require exactly 256 characters.
