TCharacter.ConvertToUtf32 converts a UTF16-encoded Unicode character to a Unicode32 character. This is the opposite of TCharacter.ConvertFromUtf32. The function exists in several overloaded versions, to be able to present the Unicode character in one of 2 ways:
If AIndex is not a valid character index in the string AString, an EArgumentOutOfRangeException exception is raised. If the character at that position is not complete, an EArgumentException exception is raised.
