Add square brackets in subject field. How to do it?

Hello,
I’m creating a form to let user request an intervention from our part. The subject should contain an incremented dynamic number and be structured as this :

[CASE-#485-doe] Intervention request for product(s) A, B, C

As you can see, I want brackets showing in the subject.
In my CF7 form, if I write :

1. [CASE-#[cf7-counter]-[your-last-name]] Intervention request for product(s) [prod-id]
   I get a missing end bracket :
   [CASE-#485-doe Intervention request for product(s) A, B, C
2. [[CASE-#[cf7-counter]-[your-last-name]]] Intervention request for product(s) [prod-id]
   I get a wrong counter number :
   [CASE-#1-doe] Intervention request for product(s) A, B, C
3. [[CASE-#[cf7-counter]-[your-last-name]] Intervention request for product(s) [prod-id]
   I get the ascii code :
   [CASE-#485-doe] Intervention request for product(s) A, B, C
4. '['[CASE-#[cf7-counter]-[your-last-name]']' Intervention request for product(s) [prod-id]
   I get the quoted brackets :
   '['CASE-#485-doe']' Intervention request for product(s) A, B, C

Is there a way to add Square brackets out of a shortcode and display it in the final email?
