Step 1: Determine the UTF-8 encoding bit layout
The character ⑈ has the Unicode code point U+2448. 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+2448 to binary:
00100100 01001000. 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 10001000

Description
The Unicode character U+2448, also known as the OCR DASH (Optical Character Recognition Dash), is a typographic symbol that plays a crucial role in digital text processing and layout. This non-printing control character is specifically designed to assist Optical Character Recognition (OCR) software in distinguishing between separate words or elements in scanned documents. It helps OCR algorithms identify text boundaries, improving the overall accuracy of text conversion from images or other non-textual formats. The OCR DASH is commonly used in conjunction with other control characters, such as U+2420 (NBSP - Non-Breaking Space) and U+200B (ZERO WIDTH SPACE), to ensure precise text layout and formatting in digital environments. Although this character is not visible to users, it serves a vital function in the process of converting analog information into machine-readable text.
