Step 1: Determine the UTF-8 encoding bit layout
The character ¡ has the Unicode code point U+00A1. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of
0x0080to0x07ff.
Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format:110xxxxx 10xxxxxx

Convert the hexadecimal code point U+00A1 to binary:
10100001. 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:
11000010 10100001

Description
The Unicode character U+00A1, also known as the Inverted Exclamation Mark (¡), plays a unique role within digital text communication. Primarily used to denote irony or sarcasm, its visually distinct appearance—flipped compared to the traditional exclamation point—makes it an essential tool for conveying nuanced emotions in written language. Although not commonly found in everyday text, this character holds significance in specific cultural contexts and literary works where such subtleties are crucial for effective communication. The Inverted Exclamation Mark belongs to the Latin-1 Supplement Unicode block (U+00A0 to U+00FF), a versatile collection of 256 characters (128 to 255) that serve various text formatting and typography purposes. This Unicode block was designed to extend the basic Latin character set, thereby enhancing the readability and overall appearance of text documents across a wide range of applications, from professional documents to creative writing. In technical terms, the Inverted Exclamation Mark falls under the General Category Po (Other Punctuation), has a canonical combining class of 0, and its Bidi Class is ON (Right-to-Left Embedding or Isolate). Its mirrored property is set to N, meaning it does not have a mirrored counterpart in certain scripts. For further details about this character and other Unicode characters, consult the official Unicode Standard documentation.
