Raw string coloring

[BMBurstein]

I just discovered a cool feature by accident: If I wrap my raw string containing sql in R"sql(...)sql" I get sql coloring in the string. This is (in my opinion) a really cool feature, but it seems to only work for sql.

1. Is this feature documented anywhere? I ran into it by accident
2. Can this be extended to other languages?

See here an example of what I am talking about:

It's implemented at https://github.com/jeff-hykin/better-cpp-syntax/blob/db3f4e4a5d8335b2f6d689bec490c23f8313630f/main/patterns/raw_strings.rb which is used by VS Code and not our C/C++ extension.
