If you want to transform your codes to Unicode strings we recommend you this article. RAD Studio, Delphi & C++ Builder uses Unicode-based strings: that is, the type String is a Unicode string ( System.UnicodeString) instead of an ANSI string. More information about the structure of Unicode Strings can be found here. String atoms have the following properties: The values of string atoms are in the range 0xC000 (MAXINTATOM) through 0xFFFF. CLANG / C++ Builder / GNU C / VC++ compilers, IDEs are using this standard for GUI forms to support all languages to provided applications in global. When applications pass null-terminated strings to the GlobalAddAtom, AddAtom, GlobalFindAtom, and FindAtom functions, they receive string atoms (16-bit integers) in return. In modern C++ nowadays there are two types of strings used array of chars (char strings) and UnicodeStrings (WideStrings and AnsiStrings are older, not compatible with all features now). UnicodeStrings are being used widely because of support to languages world wide and emojis. Unicode standard for UnicodeString provides a unique number for every character (8, 16 or 32 bits) more than ASCII (8 bits) characters. In Modern C++, strings and wide strings can be used, we highly recommend you to use unicode strings. What else should I know about wide strings in C++? Wide strings are the instantiation of the basic_string class template that uses wchar_t as the character type. In another terms wstring stores for the alphanumeric text with 2 or 4 byte chars. ![]() Wide strings are the string class for wide characters represented with wstring and alphanumeric characters are stored and displayed in string forms. What you need to know about wide strings in C++ Here are the string types defined in std::pmr namespace with their char type and C++ standard String Type
