There is a backslash in a URI.
Although backslashes are acceptable in theory within URLs, in practice they are usually due to following the Windows custom of using backslashes as path separators instead of using forward slashes (the accepted path separator in a URI), or the Unix custom of escaping special characters by backslashes, instead of using percent-escaping (the accepted URI format).
