Detailed Description

wxUString is a class representing a Unicode character string where each character is stored using a 32-bit value.

This is different from wxString which may store a character either as a UTF-8 or as a UTF-16 sequence and different from std::string which stores a string as a sequence of simple 8-bit characters and also different from std::wstring which stores the string differently depending on the definition of wchar_t.

The main purpose of wxUString is a to give users a Unicode string class that has O(1) access to its content, to be identical on all platforms and to be easily convertable to wxString as well as other ways to store strings (C string literals, wide character string literals, character buffer, etc) by providing several overloads and built-in conversions to and from the various string formats.

wxUString derives from std::basic_string<wxChar32> and therefore offers the complete API of std::string.
