Step 1: Determine the UTF-8 encoding bit layout
The character ⑁ has the Unicode code point U+2441. 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+2441 to binary:
00100100 01000001. 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 10010001 10000001

Description
U+2441 is the Unicode character code for the "OCR Chair" symbol, which is commonly used in digital typography to indicate a position marker for optical character recognition (OCR) software. This specialized character assists in identifying the orientation and placement of text elements during the OCR process, ensuring greater accuracy and precision when converting images or scanned documents into machine-readable formats. In its role as an OCR marker, U+2441 helps to optimize the performance and reliability of optical character recognition applications across various industries, including document management, publishing, and archiving. While it may not have a direct cultural or linguistic significance, this technical symbol plays a critical part in facilitating efficient information processing and preservation in our increasingly digital world.
