JEP 293: Guidelines for JDK Command-Line Tool Options - @-files

I'm facing some troubles with the content of the @-files and the  
documentation[1] isn't helping me yet.

First of all it doesn't mention the encoding, I assume it is the OS  
specific encoding.

I'm facing issues with a long --module-path on Windows.
I noticed I can use the "normal" filename (not a URI or URL), but I need  
to escape the \ with an \, resulting in
(and much more entries)

You can use a space or a newline as separator between arguments, but if an  
argument contains spaces it must be surrounded with double quotes.
However, the path to my local (Maven) repository contains a space and  
JLink is complaining it cannot find these dependencies. It seems like I  
need to escape spaces too, though I haven't figured out how to do that.
Changing my local repo to a space-less path works. There should be a way  
to handle spaces, but how?

I'm not sure if there are other specific things to keep in mind when  
writing @-files, but it would be nice if that would be explained it the  
jep too.
