Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+2E75. 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+2E75 to binary:
00101110 01110101
. 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 10111001 10110101

Description
U+2E75 is a character in the Unicode standard, representing the "Combining Enclosed Superscript Digit Zero." This typographical symbol is commonly used in digital text to denote a superscripted zero that appears within enclosing parentheses or other symbols. Its primary function is to assist with mathematical notation, particularly when expressing algebraic expressions where the base value is zero, such as in big O notation or set theory. The character ensures accurate and clear communication of these complex concepts in both academic and professional contexts. There is no significant cultural, linguistic, or historical context associated with U+2E75. Its role in digital text remains primarily technical, serving a functional purpose within mathematical and scientific expressions.
