I was looking at a site for a client and a link checker I used threw a broken link error when it encountered a URL with an apostrophe in it (it's a town name). The URL returns the page ok, but now I'm not sure what to do. I guess that the use of an apostrophe in the URL is not great, but will it have an adverse effect on the page being indexed/crawled ? So - leave it as is or drop the ' ??
