Step 1: Determine the UTF-8 encoding bit layout
The character ℉ has the Unicode code point U+2109. 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+2109 to binary:
00100001 00001001. 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 10001001

Description
The Unicode character U+2109, also known as the Degree Fahrenheit symbol, is a vital typographical element commonly used in digital text to denote temperature measurements in the Fahrenheit scale. This symbol serves a crucial function in scientific documents, weather forecasts, and engineering fields where precise temperature specifications are required. The Degree Fahrenheit symbol is derived from an older, similar symbol for the degree Centigrade (U+2103), with its design influenced by early-modern European typography. Although both symbols may appear visually similar, they represent distinct units of measurement and should be used accordingly in digital text to ensure accurate communication of temperature values.
