In Google SERPS, the text URL (without the [
)...] is shown below the description. Sometimes, this text URL seems to have a spurious space character after one of the "/" characters, usually (but not always) before the page name. This prevents copying and pasting the URL. The actual link to the page works fine, it's just the non-functional text URL that's affected. Not all results show this.
I'm sure this has been discussed before, but despite using all my search-powers (ha!) I couldn't find a relevant thread.
