How to replace a brace using sed in linux

Question

Suppose I have a file (say a.txt) whose text reads :

{I have a dream today}

I want to replace the braces so that the file a.txt now looks like :

I have a dream today

I tried using the sed expression sed -i {s/{}//g}, but it doesn't work. Is there a smart way to do this?

Thanks in advance.

In this scenario you want to use a character class, and include both brackets { and } in it:

sed -i 's/[{}]//g' a.txt
