Step 1: Determine the UTF-8 encoding bit layout
The character ⤌ has the Unicode code point U+290C. 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+290C to binary:
00101001 00001100. 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 10100100 10001100

Description
The Unicode character U+290C, also known as the "Leftwards Double Dash Arrow," is a specialized symbol used primarily in mathematical equations and scientific notation within digital text. Its typical usage is to represent a directional change or movement, specifically a decrease in value or a leftward shift along an axis. This character is often employed in equations involving vector calculus, where it signifies a rotation of 180 degrees about the vertical axis. Due to its role in mathematical notation, U+290C is essential for maintaining accuracy and clarity in technical documents, particularly those involving physics, engineering, or computer science. Although not as widely recognized as other Unicode characters, the Leftwards Double Dash Arrow holds significance within its niche field of application, contributing to the precision and efficiency of communication within these specialized disciplines.
