Step 1: Determine the UTF-8 encoding bit layout
The character has the Unicode code point U+0FFD. 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+0FFD to binary:
00001111 11111101. 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:
11100000 10111111 10111101

Description
The Unicode character U+0FFD, also known as CHARACTER 0FFD, is a unique symbol that holds significance in the realm of digital text processing and encoding. Its primary role is to serve as a replacement character for undefined control codes or to indicate an error in the encoding process. In essence, it functions as a catch-all for instances where a specific character code has not been defined within the Unicode Standard. Despite its seemingly obscure nature, U+0FFD plays a crucial role in ensuring smooth text processing and communication across various platforms and systems. The character is particularly essential when dealing with older or less common encodings, as it provides a fallback solution for cases where defined characters may not be available or recognized. While the cultural, linguistic, or technical context of U+0FFD might not be as widely known compared to other well-known Unicode characters, its importance lies in its ability to maintain text integrity and compatibility within digital systems, thus contributing to a more seamless global communication experience.
