Right now I have a regular expression to pick up most characters
([/\w\.-]+)$
However I would like it to also be able to find phrases with the ® symbol such as sdj-0s®. The ® character can appear anywhere any number of times. For example, searching for "www.samplesite.com/eng/sdj-0s®-wer®". Ideally we'd like to account for other possible Unicode characters as well.
What would be the best regex expression to achieve this?
