Step 1: Determine the UTF-8 encoding bit layout
The character ⨺ has the Unicode code point U+2A3A. 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+2A3A to binary:
00101010 00111010
. 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 10101000 10111010

Description
The Unicode character U+2A3A, known as the MINUS SIGN IN TRIANGLE (−△), is a mathematical symbol used in digital text to denote both subtraction and a geometric figure. This unique symbol combines two fundamental mathematical concepts - subtraction and the triangle, which are essential for various calculations and geometrical representations in science, engineering, and mathematics. The MINUS SIGN IN TRIANGLE is particularly useful in contexts where visual differentiation of negative numbers or mathematical operations is crucial, such as in computer programming, scientific notation, and technical documentation. Although its usage is not widespread due to potential readability issues, the MINUS SIGN IN TRIANGLE contributes to a more expressive typography for those who appreciate its distinctiveness.
