Research direction

Reproduce the failure using the C++ example with tpl.Load and RenderAsString, comparing the expressions with and without the space before }}. Trace the template-expression parsing reached by that example, then add a regression test showing that the no-space form renders successfully.

Written by the indexing model from the issue text.

Description

A single example like this will cause a render error ( tested on Release 1.3.1)

void minimum_example() {
    
    jinja2::Template tpl;
    
    tpl.Load("{{ 'Hello World!' + '\n'}}");
    
    std::cout << tpl.RenderAsString({}).value() << std::endl;
    
}

I found the issue could be avoided if a space is inserted:

tpl.Load("{{ 'Hello World!' + '\n' }}");

But considering template file is usually not so space sensitive and accurate, I wonder if this is something that can be fixed?
