Step 1: Determine the UTF-8 encoding bit layout
The character ? has the Unicode code point U+003F. In UTF-8, it is encoded using 1 byte because its codepoint is in the range of
0x0000to0x007f.
Therefore we know that the UTF-8 encoding will be done over 7 bits within the final 8 bits and that it will have the format:0xxxxxxx
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+003F to binary:
00111111. 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:
00111111

Description
The Unicode character U+003F, commonly known as the Question Mark (?), plays a significant role in digital text communication. This typographical symbol is widely used in written English to indicate open-ended queries, prompts for additional information, or uncertainty. Its usage transcends linguistic barriers and is employed across various languages that utilize the Latin script. In syntax, the Question Mark constructs interrogative sentences, making it an essential tool in conveying inquiry or doubt. It can be paired with other punctuation marks like quotation marks or parentheses for added emphasis or clarification. The Question Mark's relevance lies in its versatility across informal and formal contexts, making it a key component of digital text in the rapidly evolving world of typography and communication. This character is part of the Basic Latin Unicode block, which encompasses 128 essential characters from U+0000 to U+007F. The Basic Latin Unicode block, historically rooted in the ASCII character set, has evolved to accommodate modern needs and remains integral to digital communication.
