Step 1: Determine the UTF-8 encoding bit layout
The character ェ has the Unicode code point U+30A7. 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+30A7 to binary:
00110000 10100111. 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 10100111

Description
U+30A7 is the Unicode character code for Katakana Letter Small E (小英). This character is primarily used in the Japanese writing system, where it represents a specific sound in the Katakana script. The Katakana script itself is one of two phonetic syllabaries used in the Japanese language, the other being Hiragana. Katakana is often employed to transcribe foreign words, especially those from English, as well as proper nouns and technical or scientific terms. U+30A7, specifically, serves a critical role in enabling accurate pronunciation of these words, making it indispensable in the digital text realm for Japanese speakers and learners alike. Its significance extends beyond linguistic boundaries, as it plays a part in preserving and propagating cultural and technical knowledge across diverse languages and fields.
