I've searched the document. There is a GetStringFactoryReturnTypeId method, but there is no GetStringFactory. Sometimes getting the string factory from the engine can reduce direct dependency between different code modules. For example, I can create a script string without include an additional custom string header.

I hadn't thought of that before. Sure, this can easily be added to the interface. I'll include it for the next release after 2.37.0.

I've implemented this now in revision 2939.
