How data is manipulated in unicode charset?

Data in a Unicode charset is manipulated by encoding characters into specific byte sequences that represent them in digital form. Unicode defines a unique code point for each character, which can be encoded using various schemes like UTF-8, UTF-16, or UTF-32, each varying in how they represent characters using bytes. When manipulating text data, operations such as searching, sorting, or transforming characters are performed on these encoded byte sequences while ensuring that the integrity of the character representation is maintained across different systems. Tools and libraries often provide functions to handle encoding and decoding, facilitating seamless data manipulation in Unicode.
