Compiling `gr()` the core is not reset. The error is this:

```julia
using Plots
gr()
x=0:0.01:2*π
y=sin.(x)
plot(x,y)

```

```julia

Could you please try the following:

```julia
using GR
x = 0:0.01:2*π
y = sin.(x)
plot(x, y)

```

… and then:

```julia
savefig("test.svg")

```

If this works, please quit Julia and then (in the `Command Prompt`) simply enter

```julia
test.svg

```

… which should display the above SVG file.

Thank for the comment.

When I enter:

```julia
savefig("test.svg")

```

the same error occurs:

```julia

In the Atom environment the error above appears.

However, when compile these codes in the executable, the graph is done, but an error appears:

```julia
julia> plot(x,y)

```

Almost there…

The only explanation I have is, that there is a Unicode Problem with your account name. I could not reproduce it on Windows 10. Is there another account on your system (without UTF characters in the account name)?

Do you think if I solve the unicode problem the problem is solved?

Is the folder name “Usário”? Do you know how to change it?

Is this related to the atom editor too?

Could you please try `savefig("test.pdf")` and/or `savefig("test.png")`?

That’s strange: The following script works fine on Windows:

```julia
using GR
plot(randn(10))
savefig("delta-Δ/pi-π.svg")

```

Somehow I am now at a loss …

@jheinen, fyi `savefig("delta.svg")` worked fine on Win10 Julia 1.6.0-beta1.0 but not with the special characters:

```julia
julia> savefig("delta-Δ/pi-π.svg")
GKS: file open error (delta-Δ/pi-π.svg)
open: No such file or directory
GKS: can't open SVG file
open: No such file or directory

Does `savefig("pi-π.svg")` work? I don’t understand why it works on my Windows 10 VM - even on the C:\ device. So it’s not related to some special virtual files system …

@jheinen, yes `savefig("pi-π.svg")` does work. `savefig` is not supposed to create a new directory `delta-Δ/` if this does not exist.

The problem is actually the name of account name. I cannot change. There is a way to move the past `/.julia` to other local? I cannot to do this.
