I think it's the editor itself. I think the plugin Sourceror allows input of code ... but allowing users to do that is quite a hazard for the site's security
If you simply want the code to be displaed, not executed, check out your input editor's setting. Many, like tiny MCE, allow
[code:1]code segments /(){[]}\[/code:1]
