0x93

0x93 is a hexadecimal literal representing the decimal value 147. In computing, such hex values are commonly used to denote byte values, memory contents, or constants in source code and data streams.

In Windows-1252, a widely used legacy encoding on Windows systems, the byte 0x93 maps to the left double quotation mark, U+201C. The adjacent byte 0x94 maps to the right double quotation mark, U+201D. By contrast, in ISO-8859-1, 0x93 is a C1 control code rather than a printable character. This difference helps explain why text containing 0x93 can appear as different symbols or be garbled when viewed under mismatched encodings.

Unicode and UTF-8: The character at U+201C is the typographic left double quotation mark. In UTF-8, this character is encoded as three bytes: E2 80 9C. Understanding this is important when converting text between encodings or debugging encoding-related issues.

Practical usage and pitfalls: The byte 0x93 frequently appears in data originating from Windows environments. If such data is decoded using a non-Windows encoding, the left double quotation mark may be displayed incorrectly, leading to punctuation inconsistencies. As a generic hex value, 0x93 is simply 147 in decimal, but its significance is often tied to its role in Windows-1252 text as a stylized quote.
