Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+245F. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800to0xffff.
Therefore we know that the UTF-8 encoding will be done over 16 bits within the final 24 bits and that it will have the format:1110xxxx 10xxxxxx 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+245F to binary:
00100100 01011111. 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:
11100010 10010001 10011111

Description
The Unicode character U+245F, also known as CHARACTER 245F, is a specialized symbol primarily used in digital text for representing a unit of electrical power called the Milliwatt (mW). In electronic engineering and scientific contexts, this character serves as a concise way to denote this specific unit of measurement. Although it may not be widely recognized outside these fields, its accurate usage is crucial for clear communication of technical information related to energy consumption in electronic devices or systems. The use of U+245F demonstrates precision and adherence to established conventions within the scientific and engineering community, thereby contributing to the clarity and reliability of the information being conveyed.
