The string type is a direct interface to the string type in C#.
Strings are considered a value type in the FrooxEngine data model, but an object in the ProtoFlux data model.
Strings are sequences of chars, and as such are UTF-16 encoded. When representing characters that are outside the Basic Multilingual Plane, a pair of two chars is used, known as a surrogate pair. Due to this, not every character in a string may be mapped directly to one char, and this can cause confusion when using ProtoFlux nodes on strings containing non-BMP characters. Additionally, stray surrogate characters that are not part of a surrogate pair may not behave as intended.
Strings may be used a primitive form of 16-bit integer arrays in ProtoFlux by way of the Get Character node and To UTF16 node.
