You may need to show us what you're trying to do. Curly brackets within double-quoted strings have special meaning only when attached to some construct that looks relevant to Perl's "double quote like interpolation", such as "$hash{indexing}" and "@{$dereferencing} (for example). If you're having trouble printing the brackets you may either use single quotes to eliminate interpolation, or make your string not look like one of the special cases that makes Perl think you're interpolating.

But if you show us your issue we may be able to suggest a solution.

perlop has a good discussion on quoteing behaviors.
