Java: need regex help

I want to match a word that might have a special character within it.
For eg:  
Paris'
'Paris
Pa'ris
Paris%
P'ar*s%
Paris  (in this case no special character)

Hi Ozo,
What if the word Paris was just an eg?
I mean what if i wanted to match some random phrase which has a combo of letters and special characters.

Is there anything the regex should not match?

Are you saying you want to find a match for a given word whether or not it has special characters or do you want to find matches for all words that have special characters or something else entirely. Perhaps you can provide a literal explanation of what your search criteria is.

.*
Is one one regex that matches every example you've given,
as well as some that you have not given.
I can't tell whether or not it meets your needs in the cases you have not specified.
