Or you can use [{] and [}], which i find easier because \{....\} are 
special instead of { } in some regular expression languages. This works
for ( ) too, since \(...\) is a capturing group in sed, vi, etc., so
[(] and [)] work pretty much everywhere.

You still have to write [{{] and [}}] unless you use a variable; i'd
recommend using a variable, though, so you can give it a name that's in
the problem domain, such as "superscript-regex".

As to Mike Kay's typographical point, one can to some extent use the
maths fonts, but it's tedious and often ugly, depending on the browser:

I'd like to see presentation mathml integrated through CSS into Web
browsers, so that one could simply declare an element to have a left
brace, or fence as mathematicians call it.
