template_file rendered differently on different platforms?

[borgilb]

Terraform Version

Terraform v0.11.1
+ provider.google v1.4.0

Terraform Configuration Files

data "template_file" "startup_script" {
  template = "${file("templates/startup_script.txt.tpl")}"
  vars {
    instance_name = "blahblah"
  }
}

resource "google_compute_instance" "instance01" {
  ...
  metadata_startup_script = "${data.template_file.startup_script.rendered}"
}

Template file

echo ${instance_name } > /tmp/one.txt
echo ${instance_name } > /tmp/two.txt

Debug Output

metadata_startup_script: "" => "echo blahblah > /tmp/one.txt\r\necho blahblah > /tmp/two.txt\r\n"

Expected Behavior

Unix style file encoding? I found that for some reason, whenever I rendered my startup-script from a template GCE would not execute it. Not rendering it from a template and just passing in text did work. When I looked at the startup-script value for the GCE instance in the GCP console though it looked identical when doing it either way. I suspect its using windows style file encoding and GCE doesn't like that. I haven't confirmed this, but I bet if I ran terraform apply from a linux or mac it would work.

Actual Behavior

GCE isn't running my startup-script and I'm certain it has to do with the file encoding. Is there a way to set the file encoding?

Steps to Reproduce

Pass metadata_startup_script a multi-line template on a windows box

changing the file to have unix line endings works.
