How do I escape an opening square bracket in an ARM template?

I have something like the following under properties for an application settings configuration:

"my_setting" : "[{width:1, height:2}]"

I want exactly the string contained in the value (including the square brackets) to appear on the application settings. Unfortunately, the opening square bracket indicates a function and the deployment throws me an exception due to it. How can I escape the beginning square bracket?

The escape sequence for ARM templates is the left bracket itself (i.e. just put two together)

"my_setting" : "[[{width:1, height:2}]"

How can I escape the beginning square bracket?

We could use the concat function to avoid to using the special characters 

"variables": {
   ...
    "left": "[",
    "right": "]",
    ...
  },

Please have a try to use following code. It works correctly on my side.

"my_setting": "[concat(variables('left'),'{width:1, height:2}',variables('right'))]",
