Thanks for this! I'm Spanish, live in Germany, and speak English regularly with other non-native speakers: this causes a lot of confusion.
What I've ended up doing:
- Parentheses ()
- Braces {}
- Brackets []
It's good to know that, however economic this might look to me, it's still likely to be misunderstood or at least ambiguous even to native speakers.
UK:
- Brackets ()
- Curly brackets {}
- Square brackets []
US:
- Parentheses ()
- Curly braces {}
- Square brackets []
