Step 1: Determine the UTF-8 encoding bit layout
The character イ has the Unicode code point U+30A4. 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+30A4 to binary:
00110000 10100100. 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 10100100

Description
U+30A4 is the Unicode code point representing the Katakana letter "イ" (pronounced as "i"). This character plays a significant role in digital text, particularly in the Japanese writing system. The Katakana script, one of the three scripts used in the Japanese language alongside Hiragana and Kanji, is primarily employed for transliterating foreign words and names, as well as denoting specific grammatical functions. U+30A4 "イ" is part of the Katakana Extended character set, which was introduced to support additional characters required for modern Japanese usage, and includes other unique Katakana letters not found in earlier sets. While it may seem like a less significant character due to its limited usage compared to Hiragana and Kanji, U+30A4 "イ" remains an essential building block in the rich tapestry of the Japanese language, facilitating communication with foreign words and names while also contributing to the linguistic versatility of the writing system.
