Step 1: Determine the UTF-8 encoding bit layout
The character Ё has the Unicode code point U+0401. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of
0x0080to0x07ff.
Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format:110xxxxx 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+0401 to binary:
00000100 00000001. 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:

Description
U+0401 is the Unicode character code for Cyrillic Capital Letter Io (И), which represents the 19th letter of the Russian alphabet. In digital text, it plays a vital role in representing and encoding the Cyrillic script, enabling communication and information sharing across multiple languages that use this writing system. The Cyrillic script has its roots in the Greek and Latin alphabets, with adaptations and modifications over time, including the development of the Slavic Cyrillic script by Saints Cyril and Methodius in the 9th century. Io is pronounced as a voiced palatalized postalveolar fricative and holds importance in various Russian words and names. As part of the Cyrillic alphabet, it contributes to the cultural heritage and linguistic identity of numerous Slavic-speaking countries, including Russia, Ukraine, Belarus, Bulgaria, Kazakhstan, Kyrgyzstan, and others.
