Step 1: Determine the UTF-8 encoding bit layout
The character オ has the Unicode code point U+30AA. 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+30AA to binary:
00110000 10101010. 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 10101010

Description
The Unicode character U+30AA represents the Katakana letter 'Ō' (ヲ), which is a component of the Japanese writing system. In digital text, this character serves as an essential element for accurate transcription and translation of Japanese content, facilitating communication and information exchange in various digital platforms and applications. The Katakana script is primarily used to denote native Japanese words or foreign loanwords, while the hiragana script is employed for grammatical particles and native Japanese words. As a crucial component of these scripts, U+30AA plays a significant role in preserving cultural context and linguistic nuances within digital texts. Moreover, the Katakana system contributes to the ease of learning and reading for both native Japanese speakers and non-native learners, given its phonetic nature and clear visual distinctions between characters. Overall, U+30AA (KATAKANA LETTER O) is an indispensable character in digital text that upholds cultural integrity, linguistic accuracy, and effective communication within the context of Japanese language and typography.
