Step 1: Determine the UTF-8 encoding bit layout
The character ␀ has the Unicode code point U+2400. 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+2400 to binary:
00100100 00000000
. 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 10010000 10000000

Description
The Unicode character U+2400, known as the Symbol for Null, is a rarely used typographic symbol primarily found in digital text. Its primary role is to represent the concept of 'null', a state of absence or zero value in computer science and programming. In this context, it serves as a placeholder for data that may be null or undefined. The Symbol for Null has limited cultural, linguistic, or technical significance beyond its specific role in digital text and programming. It is not commonly used outside of these specialized applications due to the absence of any established symbolic meaning or association in other fields.
