I can reproduce this behavior on Windows.  I think the issue is an extra
pair of single quotes (see below).

              ^_____________^

For reasons not clear to me, the compiler gets the file name passed in
those single quotes.  As a test, at a command prompt I can do

    xelatex -interaction=nonstopmode "\input" "foo bar.tex"

and it works, but

    xelatex -interaction=nonstopmode "\input" '"foo bar.tex"'

exits with:

    This is XeTeX, Version 3.14159265-2.6-0.99996 (TeX Live 2016/W32TeX) (preloaded format=xelatex)
     restricted \write18 enabled.
    entering extended mode
    LaTeX2e <2016/03/31> patch level 3
    Babel <3.9r> and hyphenation patterns for 67 language(s) loaded.
    ! I can't find file `'"foo bar.tex"''.
    <*> \input '"foo bar.tex"'

    (Press Enter to retry, or Control-Z to exit)
    Please type another input file name
    ! Emergency stop.
    <*> \input '"foo bar.tex"'

Does this help?

Best, Arash
