Step 1: Determine the UTF-8 encoding bit layout
The character K has the Unicode code point U+212A. 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+212A to binary:
00100001 00101010. 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 10000100 10101010

Description
The Unicode character U+212A is known as the Kelvin Sign (°K). It is a widely used symbol in scientific and engineering fields to denote the Kelvin scale of temperature, which measures absolute temperature from the lowest possible negative temperatures to zero Kelvin where absolute zero is defined as 0 K. Its typical usage in digital text is for expressing values within this scale. For instance, the boiling point of water at standard atmospheric pressure is given as 100°C or 373.15 K. U+212A is included in the Miscellaneous Technical category (block: 2420-2479) in Unicode. It's noteworthy to mention that its character code position, 212A, derives from the hexadecimal system, which utilizes the numbers 0-9 and A-F to represent numerical values. This symbol is part of a larger set of special characters used in various languages and applications for mathematical or scientific notation.
