Step 1: Determine the UTF-8 encoding bit layout
The character Ά has the Unicode code point U+1FBB. 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+1FBB to binary:
00011111 10111011. 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:
11100001 10111110 10111011

Description
The Unicode character U+1FBB, or the "Greek Capital Letter Alpha with Oxia," is a specialized typographical symbol primarily used in digital text for representing the Greek letter Alpha. Its role in digital text mainly pertains to linguistic, cultural, and technical contexts. In linguistic terms, the Alpha is the first letter of the Greek alphabet and holds significant cultural and historical importance as it forms the basis for counting and numeral systems. The inclusion of U+1FBB enables accurate representation of ancient texts, mathematical notations, and other fields requiring Greek letters in digital platforms. Its usage also caters to typography enthusiasts, scholars, and researchers working with Greek language or related studies. In technical contexts, it aids in preserving the integrity of text data by maintaining character encoding standards in Unicode.
