readUTF

readUTF is a function commonly found in programming languages and libraries that handles the reading of data encoded using the UTF-8 character encoding. UTF-8 is a variable-width character encoding capable of encoding all possible Unicode characters. The readUTF function's primary purpose is to correctly interpret a sequence of bytes that represent UTF-8 encoded characters, converting them into the appropriate internal representation for the programming language, typically a string.

When reading data from sources such as files or network streams, the encoding of that data is crucial for accurate interpretation. If the data is known to be in UTF-8, using a readUTF function ensures that multi-byte characters are correctly assembled and displayed. Without proper handling, a readUTF function would otherwise misinterpret these bytes, leading to garbled text or encoding errors.

Different programming environments may provide readUTF functionality through various means. It might be a built-in function, part of a standard library for I/O operations, or a method of a specific object designed for handling character streams. The implementation details can vary, but the core objective remains the same: to facilitate the reliable reading and processing of UTF-8 encoded text. Understanding and utilizing readUTF is essential for developers working with internationalized text or data that may originate from diverse sources.
