Step 1: Determine the UTF-8 encoding bit layout
The character 【 has the Unicode code point U+3010. 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+3010 to binary:
00110000 00010000. 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:
11100011 10000000 10010000

Description
The Unicode character U+3010, known as the Left Black Lenticular Bracket, is a specialized typographic symbol that plays a specific role in digital text. Its primary function lies in mathematical and scientific notation, where it is used to enclose and delimit sequences of content within a single entity. The Left Black Lenticular Bracket typically pairs with its right-facing counterpart (U+3011) to create an enclosure for such sequences. In this context, the character serves as an alternative to the more commonly used square or round brackets, offering a distinct visual style for specific applications. While it may not be prevalent in everyday digital text, its usage can be found in specialized fields like mathematics, computer science, and certain areas of linguistics where unique typographical representation is required.
