How to escape curly brackets or braces?

[titocosta]

I need curly brackets { } inside my message. How do I escape it to avoid confusion and errors related to variable substitution?

Hey! ICU uses single quotes as the escape character.

"Escape curly braces with single quotes (e.g. '{name'})"

I'm also adding this to the docs, thank you for mentioning this!

I have a use case wanting to have a ' before {}, how do I achieve to escape single quote itself
The translated example: View 'Content' in 'Page 4'
