Detailed Description

template<typename Type>
class NCollection_UtfString< Type >

This template class represent constant UTF-* string. String stored in memory continuously, always NULL-terminated and can be used as standard C-string using ToCString() method.

Notice that changing the string is not allowed and any modifications should produce new string.
