Step 1: Determine the UTF-8 encoding bit layout
The character ⅐ has the Unicode code point U+2150. 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+2150 to binary:
00100001 01010000. 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 10010000

Description
The Unicode character U+2150, known as the Vulgar Fraction One Seventh, is a digitally encoded typographical symbol used to represent one-seventh in digital text. Its primary role lies in providing an accurate representation of fractions within mathematical equations, recipes, and historical documents. In modern times, its usage has become less prevalent due to the availability of more flexible fractional notation in many software applications. However, it still holds significance in typography, where it helps preserve the original form and style of ancient manuscripts for scholarly purposes. The Vulgar Fraction One Seventh is an important element in the study of early European print culture, providing insights into the way fractions were represented and understood during that time.
