Step 1: Determine the UTF-8 encoding bit layout
The character ス has the Unicode code point U+30B9. 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+30B9 to binary:
00110000 10111001. 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 10111001

Description
The character U+30B9, known as "KATAKANA LETTER SU," holds a significant position within the Unicode Standard. This specific script is widely used in the Japanese writing system and plays an essential role in digital text encoding. In contrast to Hiragana, Katakana serves for rendering non-native Japanese words, foreign names, and terms borrowed from other languages. Its usage assists in differentiating between native Japanese words and foreign loanwords. The Katakana script is also employed for transcribing scientific terminology, technical jargon, and various onomatopoeic expressions. Thus, U+30B9 "KATAKANA LETTER SU" demonstrates a cultural, linguistic, and technical context in its usage within the Japanese language and digital text encoding systems.
