0xEB

0xEB is a hexadecimal byte value representing the decimal number 235. In computing, it is commonly encountered as a byte in data, machine code, or encoded text, and its meaning depends on the surrounding context or encoding scheme.

In x86 machine code, 0xEB is the opcode for a short unconditional jump, often written as JMP rel8. This single-byte opcode is followed by one signed 8-bit displacement, allowing a jump to a location within approximately -128 to +127 bytes from the next instruction. Because of its compact encoding, 0xEB is frequently seen in hand-written shellcode, obfuscated code, and compact binaries, where small control-flow changes are needed.

In character encodings, 0xEB maps to the character "ë" (Latin small letter e with diaeresis) in ISO-8859-1 and Windows-1252. In Unicode, the corresponding code point is U+00EB. In UTF-8, the character "ë" is encoded as two bytes: 0xC3 0xAB. The byte 0xEB can also appear as the leading byte of a 3-byte UTF-8 sequence for other characters, since 0xE0 through 0xEF indicate the start of a 3-byte code unit in UTF-8.

Beyond these uses, 0xEB is generally just a byte value. Its interpretation is entirely context-dependent, governed by the particular protocol, encoding, or instruction set in which it appears.
