Step 1: Determine the UTF-8 encoding bit layout
The character 。 has the Unicode code point U+3002. 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+3002 to binary:
00110000 00000010. 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 10000010

Description
The U+3002 character, also known as the IDEOGRAPHIC FULL STOP, is a unique punctuation mark found within the Unicode standard. Its primary role in digital text lies in providing a distinguishing separation between distinct sentences or ideas in Chinese and Japanese languages. Unlike its English counterpart, the period or full stop (.), which indicates a pause in thought or a completed idea, the IDEOGRAPHIC FULL STOP serves as an essential punctuation tool for written communication in East Asian languages, aiding readers to discern different sentences more effectively. In Chinese and Japanese texts, the character is typically used at the end of a line of text, indicating that the sentence has concluded. Although its usage may seem similar to the standard full stop in English, it holds distinct cultural significance and performs specific functions within the context of East Asian languages. Overall, the U+3002 IDEOGRAPHIC FULL STOP plays an important role in facilitating clear communication in digital Chinese and Japanese texts, making it an indispensable character for typography and text rendering systems that support these languages.
