Step 1: Determine the UTF-8 encoding bit layout
The character ㆙ has the Unicode code point U+3199. 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+3199 to binary:
00110001 10011001. 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 10000110 10011001

Description
The Unicode character U+3199, also known as the IDEOGRAPHIC ANNOTATION FIRST MARK, is a typographical symbol used predominantly in digital text, particularly within East Asian languages. It serves as a mark to indicate the beginning of an ideographic annotation or commentary on a specific text passage. This character holds significance in various cultural and linguistic contexts, primarily in Japan, where it is often employed in academic texts, dictionaries, and other reference materials to denote added explanation or notes related to the main text. The IDEOGRAPHIC ANNOTATION FIRST MARK plays a crucial role in maintaining clarity and organization within these texts by visually separating annotations from the primary content. In terms of technical context, U+3199 is part of the Japanese Extended-A (JpanExtA) Unicode block, which consists of characters unique to the Japanese writing system. Overall, the IDEOGRAPHIC ANNOTATION FIRST MARK is a vital typographical element within specific cultural and linguistic spheres, contributing to effective communication in digital text.
