Step 1: Determine the UTF-8 encoding bit layout
The character ␅ has the Unicode code point U+2405. 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+2405 to binary:
00100100 00000101. 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 10010000 10000101

Description
The Unicode character U+2405 represents the "Symbol for Enquiry" in digital text. This enquiry symbol is primarily used to request information or clarification in text-based communication systems, especially in technical documents and programming contexts. Its usage dates back to the days of teletypes and telex machines, where it was employed to prompt users to respond with necessary details. Although its use has diminished in modern digital communication due to the prevalence of more versatile symbols like question marks and em dash, it still holds a place of significance for those who work within technical or specialized fields that require specificity in written interactions.
