Step 1: Determine the UTF-8 encoding bit layout
The character ℯ has the Unicode code point U+212F. 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+212F to binary:
00100001 00101111. 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 10000100 10101111

Description
The Unicode character U+212F represents the "SCRIPT SMALL E" in digital text. This character is primarily used in typesetting and text formatting to create a lowercase cursive script 'E' for aesthetic or stylistic purposes. Its typical usage can be observed in various design projects, including calligraphy, handwritten-style fonts, and historical documents that require an E with a specific script or style. The character does not have any notable cultural, linguistic, or technical context outside of its role as an alternate form of the lowercase letter 'E'. In digital typography, U+212F provides designers and authors with additional flexibility in expressing their creative vision through the use of a script variant of the letter.
