How do you add a space in the display name of an iOS application?

Hi everyone,
How do you add a space in the display name of an iOS application?
so far i have tried:

proj.SetBuildProperty(targets, "CFBundleDisplayName", "Monkey's" + "   " + "World");
proj.SetBuildProperty(targets, "Bundle display name", "Monkey's" + "   " + "World");
proj.SetBuildProperty(targets, "CFBundleDisplayName", "Monkey's" + "\x2008" + "World");
proj.SetBuildProperty(targets, "Bundle display name", "Monkey's" + "\x2008" + "World");

It looked good in TestFlight, but the display name of the app when it is installed still does not have a space.
The builds are all made using unity cloud.

Do you guys have any solutions, or can point out if i missed something?
Thanks in advance!

CFBundleDisplayName goes into info.plist, not into xcode project

Thank you for the response,

How do i modify the info.plist considering that i build and upload the game using unity cloud?

Note that if an app name is longer than a few characters, iOS Home Screen will shrink the whitespaces in favor of showing all the characters. If no spaces are left, the name will be truncated with ellipses.
