cygwin path with space as source path does not work

[MoritzLoewenstein]

When using a cygwin path with a space in it as a source, rsync will error out with error code 23.
I tried the following things:

• escape space with backslash
• modify rsync.js and put the source arguments in quotes (i tried single and double quotes)

I will try to resolve this issue but I am currently out of ideas.

Fixed it, replacing the space with a questionmark works. This is my function:

function windowsPathToCygwinPath(dirPath) {
	// get diskSign and rest of dirPath
	const diskSign = dirPath[0].toLowerCase();
	dirPath = dirPath.substr(2);

	// replace backslashes with forward slashes
	dirPath = dirPath.split(path.sep).join(path.posix.sep);

	// prepend 'cygdrive'
	dirPath = `/cygdrive/${diskSign}${dirPath}`;

	// replace space with questionmark to escape it
	dirPath = dirPath.replace(/ /g, '?');

	return dirPath;
}
