Особливості представлення символів unicode у мові програмування C#

Abstract

This research focuses on the specifics of Unicode character representation in the C# language in the .NET environment. Modern software systems actively work with text data that may contain characters from different languages, special characters, and emojis. In C#, characters are stored using the char type, which is based on UTF-16 encoding. The principles of representing Unicode characters in UTF-16 encoding are analysed, in particular the difference between a Unicode character and a UTF-16 code unit. Special attention is paid to characters that are outside the basic multilingual plane and are encoded using a surrogate pair. The practical implications of these features for software development are discussed, in particular possible errors during text string processing.
