Step 1: Determine the UTF-8 encoding bit layout
The character Å has the Unicode code point U+212B. 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+212B to binary:
00100001 00101011. 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:
11100010 10000100 10101011

Description
The Unicode character U+212B, known as the Angstrom Sign (Å), holds a significant role in scientific and technical domains. It is commonly used to denote the unit of measurement for the Angstrom, which represents a unit of length equal to one ten-billionth of a meter (10^-10 m). The character's usage predominantly revolves around physics, chemistry, and other fields where atomic dimensions are discussed. The Angstrom Sign is part of the "Mathematical Operators" category in Unicode, further highlighting its functional role in digital text. In the context of typography, it is often used in conjunction with numerical values to signify the measurement scale, aiding readers in understanding and interpreting scientific information accurately.
