How do I escape correctly the quotation marks in

```julia
C:\Users\mzaffalon>julia -e 'println("hello world")'

```

on a Windows machine? The line above gives

```julia
ERROR: syntax: character literal contains multiple characters
Stacktrace:
 [1] top-level scope
   @ none:1

```

```julia
julia -e "println(\"hello world\")"

```

works for me.

Related to this: I would like to start a GUI that uses [`Gtk.jl`](https://github.com/JuliaGraphics/Gtk.jl) by double clicking on a batch file; at the same time after the GUI starts, I would like to have the REPL open. I don’t want to put the script below in the startup file, so I call `julia gui.jl` at the command line where `gui.jl` contains

```julia
using Gtk
win = GtkWindow("GUI")
push!(win,GtkButton("Click Me"))
showall(win)

if !isinteractive()
    @async Gtk.gtk_main()
    Gtk.waitforsignal(win,:destroy)
end

```

as suggested in the manual [Non REPL Usage](https://juliagraphics.github.io/Gtk.jl/latest/manual/nonreplusage/#Non-REPL-Usage-1). However no interactive REPL is started.

If I remove the `if !isinteractive() ... end` statement, and I start the script using `julia -L gui.jl`, I get a responsive REPL together with the GUI.

Is there a better way of doing this or is the `-L` option meant for this purpose?
