According to RFC 1738:

"...only alphanumerics, the special characters "$-_.+!*'(),", and reserved characters used for their reserved purposes may be used unencoded within a URL."
 

You would need to add open and close quotation in the URL for the Local Database to be successfully build or install, for example:


"www.test.com/!/"  

So in your Local Database file, the URL with and without special characters will look like the one below:

define category one
"www.test.com/!/"  
www.test.com/test/
end
