Step 1: Determine the UTF-8 encoding bit layout
The character ㎝ has the Unicode code point U+339D. 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+339D to binary:
00110011 10011101. 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 10011101

Description
The Unicode character U+339D, also known as SQUARE CM, is a typographic symbol that primarily serves to represent square units in digital text. Its typical usage can be found within mathematical equations or technical documentation where precise measurement conversions are necessary. In particular, the SQUARE CM character is often utilized to indicate the conversion of cubic millimeters (cm³) into square centimeters (cm²). Although not widely used outside of specific technical contexts, this character holds significance for those working in fields such as engineering, architecture, or scientific research. The SQUARE CM symbol helps maintain clarity and accuracy when conveying spatial measurements, ensuring proper understanding and minimizing potential errors.
