Step 1: Determine the UTF-8 encoding bit layout
The character ◟ has the Unicode code point U+25DF. 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+25DF to binary:
00100101 11011111. 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 10010111 10011111

Description
The Unicode character U+25DF, known as the LOWER LEFT QUADRANT CIRCULAR ARC, is a specialized typographic symbol primarily used in digital text for drawing geometric shapes or outlining specific areas within a larger design. In terms of its role, it serves to create a visual representation of an arc that begins at the top left quadrant and curves downwards towards the right side. This character can be found within the Miscellaneous Technical (UTF-16) block of Unicode. While U+25DF does not have any specific cultural or linguistic associations, it plays a vital role in technical documentation and digital design, providing a precise tool for defining circular sections when drafting diagrams, maps, flowcharts, or other visual representations that require an easily identifiable arc-shaped boundary. Due to its highly specialized use, this character is not commonly encountered outside of these niche applications, but remains an essential part of the Unicode standard for those who work with digital design or technical documentation.
