I'm sorry, but you're example doesn't elucidate your problem (at least for me). What do you mean by "the text has been interpreted"? What does your example do that you expect it to not do or vice versa?

update:Ah, I think ccn has the sense of it. Some of the characters in your string are special WRT the regular expression engine (and presumably you want them to be treated as-is). You can use quotemeta or \Q as ccn says.
