Is there a way to show the square brackets without writing them?

Is there a way I can show ' [ ' and ' ] ' on a webpage without writing them? As I have made a small script which parses ' [ ' and ' ] ', and I was wondering is there an alternative way? Similar to doing £ to show £ ??

 

Here's a big list of symbols/characters and the code to use to make them show.
Square brackets are in "Section 2"
