Step 1: Determine the UTF-8 encoding bit layout
The character ⇋ has the Unicode code point U+21CB. 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+21CB to binary:
00100001 11001011
. 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 10000111 10001011

Description
The Unicode character U+21CB, known as the Leftwards Harpoon Over Rightwards Harpoon, plays a niche yet crucial role in digital typography. Its primary usage lies within mathematical notation systems and specific scientific fields where it is employed to denote directional changes or arrows in expressions or equations. Despite its seemingly obscure nature, this character forms part of the broader Unicode Standard, which aims to provide a unique code for every character used across all languages, scripts, and symbols. In terms of cultural, linguistic, or technical context, there isn't any direct linkage or relevance associated with U+21CB. However, it does contribute to the global consistency and accuracy in digital text communication, particularly within specialized industries and communities.
