Step 1: Determine the UTF-8 encoding bit layout
The character โ has the Unicode code point U+2148. 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+2148 to binary:
00100001 01001000
. 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 10000101 10001000

Description
The Unicode character U+2148 represents the DOUBLE-STRUCK ITALIC SMALL I (๐). This typographic symbol is predominantly used in digital text for its unique aesthetic, often in mathematical or scientific contexts where a distinct, italicized appearance is desired. In these instances, it can be employed to differentiate variables or equations from regular text, enhancing readability and clarity. Although not widely recognized in everyday language use, the DOUBLE-STRUCK ITALIC SMALL I holds significance within specialized fields such as computational linguistics and formal logic, where precise communication of concepts is crucial. The character's distinct appearance contributes to its technical value, as it combines elements of both double-struck (a typeface style that uses two lines or strokes for each character) and italic (a style with a slant to the right) typography.
