How can I pass an escaped javascript string as an argument into windows command line?

Question

I'm attempting to pass an argument to casperJS via command line. I'm executing something like

> casperjs ..\test.js " \' { function ( var ) \'     asdf"

This is loading the argument as multiple arguments

casper.cli.args[0] == "\'"
casper.cli.args[1] == "{"
casper.cli.args[2] == "function"
casper.cli.args[3] == "("
...

Notice it's a new arg everytime there's a space character - The double quotes I placed around the argument obviously don't work with the space character.

When I concat and print the arguments out I get

"\'{function(var)\'asdf"

Notice spaces all removed/truncated/whatever.

How can I escape my string so that my js app gets the actual string in 1 argument without dropping content?

Keep in mine that I need to also keep the escape integrity of the JS string I'm passing as it needs to be interpreted downstream.

I don't really understand what you want to do, if you want to get back a custom argument in your file :

Considering your command is : casperjs test yourFile.js --customArgument=" \\' { function ( var ) \\' asdf"

You get back the content in your file like that : var customArg = casper.cli.get('customArgument');

This is not what you want?
