Step 1: Determine the UTF-8 encoding bit layout
The character Ω has the Unicode code point U+2126. 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+2126 to binary:
00100001 00100110. 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 10100110

Description
The Unicode character U+2126, known as the Ohm Sign (Ω), holds a significant position in both science and technology. It represents the standard unit of electrical resistance, named after the German physicist Georg Simon Ohm. In digital text, the Ohm Sign is typically used to denote the resistance of an electrical component or circuit. Its use transcends cultural boundaries as it has become a universal symbol for this crucial aspect of electronics and telecommunications. The Ohm Sign's prevalence in these fields reflects its fundamental importance in the understanding and functioning of electronic devices.
