Step 1: Determine the UTF-8 encoding bit layout
The character ↱ has the Unicode code point U+21B1. 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+21B1 to binary:
00100001 10110001
. 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:

Description
The Unicode character U+21B1, known as the "Upwards Arrow with Tip Rightwards," serves a specific purpose in digital text by representing an arrow that points upwards with its tip pointing towards the right. In typographical terms, this symbol is often used to signify an upward motion or direction, typically in mathematical equations and diagrams, where it may represent vector transformations, angular movements, or rotations. Additionally, the character can be utilized in programming languages and algorithms for indicating specific actions, such as swapping elements in a list or array. There are no notable cultural, linguistic, or technical contexts associated with this character; however, its clear and concise representation of an upwards motion with a slight rightward inclination makes it a valuable tool for expressing certain concepts and relationships accurately within digital text.
