The [, ] and ^ are some of the "special" characters which must be
escaped, i.e. you need to put a \ in front of them in the pattern, e.g.

if you are trying to replace a string like:

^SED IS [EASY]

you'd neet to use this pattern:

/\^SED IS \[EASY\]/SED IS NOT SO EASY/

The reason you are having problems with { may be because you are trying
to put a \ in front of { or } in a pattern (e.g. to select a string like
\{tag}. Since \ is a special character too, you need to escape it in
the pattern as well, so instead of using \{ use \\{ and all should be
well.
