If you run the script below in an English Beta, it runs fine. If you run it in French, it fails - don’t know if this is also a problem in other languages, I suspect yes.
The problem is that _Font in the command string is not translated, and after that the whole command string collapses. The result is that it prints “_Font” instead of “Hello World”. If you look at the command line feedback you can see where it is erroring out; a second way to test is just to substitute “Police” for “_Font” in the command string, and then it will work in French at least.
