Step 1: Determine the UTF-8 encoding bit layout
The character × has the Unicode code point U+00D7. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of
0x0080to0x07ff.
Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format:110xxxxx 10xxxxxx
Where thexare the payload bits.UTF-8 Encoding bit layout by codepoint range Codepoint Range Bytes Bit pattern Payload length U+0000 - U+007F 1 0xxxxxxx 7 bits U+0080 - U+07FF 2 110xxxxx 10xxxxxx 11 bits U+0800 - U+FFFF 3 1110xxxx 10xxxxxx 10xxxxxx 16 bits U+10000 - U+10FFFF 4 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx 21 bits Step 2: Obtain the payload bits:
Convert the hexadecimal code point U+00D7 to binary:
11010111. Those are the payload bits.Step 3: Fill in the bits to match the bit pattern:
Obtain the final bytes by arranging the paylod bits to match the bit layout:
11000011 10010111

Description
The Unicode character U+00D7, identified as the MULTIPLICATION SIGN (code: 215), plays a vital role in digital text, particularly in mathematical expressions and scientific notation. It denotes multiplication between two numbers or variables, often replacing words such as "times" or "by." The character's origins can be traced back to the development of the Hindu-Arabic numeral system. In contemporary usage, it extends beyond mathematical contexts into fields like linguistics and computer science, symbolizing multiplication or cross products in specific algorithms. Despite its primary function, this character carries no cultural connotations but is universally recognized across various languages and platforms due to Unicode standardization. The MULTIPLICATION SIGN belongs to the Latin-1 Supplement Unicode block (code range: 128-255), a versatile collection of characters designed to enhance readability and visual appeal in text documents. This character can be found within the Basic Multilingual Plane (BMP) that accommodates most common characters.
