Step 1: Determine the UTF-8 encoding bit layout
The character ア has the Unicode code point U+30A2. 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+30A2 to binary:
00110000 10100010. 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 10000010 10100010

Description
The Unicode character U+30A2 represents the Katakana letter 'ア', or 'a'. This particular symbol is utilized predominantly in the Japanese writing system, where it serves as a member of the Katakana script, which is one of two syllabaries employed in the Japanese language alongside Hiragana. Katakana is commonly used for foreign loanwords, technical terms, and proper nouns, while Hiragana handles the majority of grammatical components and readings of native Japanese words. As a result, U+30A2 plays an essential role in enabling accurate communication and conveying the nuances inherent to the Japanese language on digital platforms. In addition to its linguistic function, Katakana script is also admired for its aesthetic appeal, contributing to various forms of visual art and design within Japanese culture.
