Trouble with AzureRM SAS Token for backend with Ampersand

I’m trying to setup a remote state in Azure. My sas_token contains & (ampersand) characters, and I don’t seem to be able to escape them. I get the following errors:

There are some problems with the configuration, described below.

The Terraform configuration must be valid before initialization so that
Terraform can determine which modules and providers need to be installed.

Error: Invalid multi-line string
PS C:\Demo> terraform init

Quoted strings may not be split over multiple lines. To produce a multi-line
string, either use the \n escape to represent a newline character or use the
"heredoc" multi-line template syntax.


Error: Unterminated template string

No closing marker was found for the string.

I’m not having any luck searching online how to get around this.
PS C:\Demo> terraform version
Terraform v0.12.23
+ provider.azurerm v2.0.0

My backend file looks like this:

terraform {
backend “azurerm” {
storage_account_name = “"
container_name = "

key = “terraform.tfstate”
sas_token = “*****&&&&…”
}
}
