0×82

0×82 is a hexadecimal byte value, representing the decimal number 130. The notation uses a multiplication sign, but in most programming and technical contexts it serves the same purpose as the more common 0x82, indicating a byte with hexadecimal value 82.

In character encoding, the meaning of the byte 0x82 depends on the encoding scheme. In Windows-1252, 0x82 maps to the character U+201A, the single low-9 quotation mark. In ISO/8859-1 (Latin-1), 0x82 is a control code and is not a printable character. In Unicode terminology, 0x82 by itself is not a Unicode code point; it is a byte value. The code point U+0082 exists as a C1 control character, which is typically non-printable.

In UTF-8, a single byte 0x82 is not a valid encoded character. UTF-8 uses multibyte sequences, and a byte in the 0x80–0xBF range must be a continuation byte rather than a leading byte. If 0x82 appears in a UTF-8 stream, it should be part of a properly formed multi-byte sequence and not stand alone.

Applications and implications: 0×82 commonly appears in low-level data representations, such as memory dumps, hexadecimal debugging, and binary file formats, where bytes are examined individually. When exchanging text data, the interpretation of 0x82 depends on the declared encoding; misinterpreting it across encodings can lead to incorrect or garbled characters.
