Step 1: Determine the UTF-8 encoding bit layout
The character ㎑ has the Unicode code point U+3391. 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+3391 to binary:
00110011 10010001. 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 10001110 10010001

Description
The Unicode character U+3391, known as the "SQUARE KHZ," is a symbol used in Japanese typography. It represents a kilohertz (kHz) value in square form. Its typical usage is within digital text to display frequency values in electrical engineering and audio technology contexts, specifically when referring to radio wave frequencies. The SQUARE KHZ symbol is essential for clear communication of these values in the Japanese language. It plays a significant role in technical documents, user manuals, and scientific literature that require precise representation of frequency measurements. Its square shape distinguishes it from similar symbols used in other languages or contexts.
