Step 1: Determine the UTF-8 encoding bit layout
The character ㆚ has the Unicode code point U+319A. 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+319A to binary:
00110001 10011010. 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 10011010

Description
The Unicode character U+319A, known as IDEOGRAPHIC ANNOTATION SECOND MARK, is an important symbol used primarily in the Japanese language for annotating ideographs or Chinese characters. Its primary role in digital text is to provide supplementary information and context about the preceding kanji character, aiding readers in understanding its meaning. U+319A is particularly essential in Japanese dictionary entries and other linguistic resources, where it clarifies the usage, pronunciation, or meaning of the character it accompanies. The Second Mark is also used to differentiate homophonic characters that may have similar pronunciations but distinct meanings. This character markup helps maintain clarity and accuracy in written communication, especially in languages with complex writing systems like Japanese.
