Step 1: Determine the UTF-8 encoding bit layout
The character ≘ has the Unicode code point U+2258. In UTF-8, it is encoded using 3 bytes because its codepoint is in the range of
0x0800
to0xffff
.
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 thex
are 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+2258 to binary:
00100010 01011000
. 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 10001001 10011000
CORRESPONDS TO·U+2258

Description
The Unicode character U+2258 represents the "∂" symbol, known as the partial differential symbol or Nabla. This mathematical symbol is commonly used in equations to represent a partial derivative, which measures how much a scalar function changes relative to a particular variable, holding all other variables constant. In digital text, it is often seen in fields such as mathematics, physics, and engineering where calculus and partial derivatives are essential concepts. The Nabla symbol has been adopted as a typographical representation of this mathematical operator, likely due to its association with the ancient Greek word for a wind instrument, which was thought to "blow" or influence change.
