Step 1: Determine the UTF-8 encoding bit layout
The character ァ has the Unicode code point U+30A1. 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+30A1 to binary:
00110000 10100001. 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 10100001

Description
U+30A1, commonly known as the "KATAKANA LETTER SMALL A," is a crucial character in the digital text domain, specifically within the Japanese language system. As part of the JIS (Japanese Industrial Standard) encoding, it holds an essential position in written communication and digital documentation. This particular Katakana script represents the sound "a" when used in phonetic contexts, contributing to the rich linguistic heritage of Japan. It is important to note that U+30A1 is not only limited to its phonetic function; it also plays a vital role in cultural contexts and traditional Japanese writing systems. Furthermore, Katakana script's simplicity and distinctiveness make it popular for foreigners learning Japanese or utilizing it for onomatopoeic words and foreign loanwords. Overall, the character U+30A1 (KATAKANA LETTER SMALL A) is an indispensable element in digital text processing, linguistic studies, and cultural appreciation of the Japanese language.
