I notice Wikipedia allows them in their URLs, is it legit or does anyone know where it will give me problems?
*'()," [not including the quotes - ed], and reserved characters used for their reserved purposes may be used unencoded within a URL.
Wildcard URLs provide a way to load content dynamically depending on the page URL. By using wildcards, you can pass the values of query string parameters directly as part of the URL path.
A URL is composed of a limited set of characters belonging to the US-ASCII character set. These characters include digits (0-9), letters(A-Z, a-z), and a few special characters ( "-" , "." , "_" , "~" ). When these characters are not used in their special role inside a URL, they must be encoded. Question mark (“?”)
No. Unfortunately you can't use ampersands (&) as part of your domain name. Characters that you can use in your domain name include letters, numbers and hyphens.
It's legit and intended to be a delimiter ; see Uniform Resource Identifier (URI): Generic Syntax
As per http://www.ietf.org/rfc/rfc1738.txt YES, you can.
...Only alphanumerics [0-9a-zA-Z], the special characters "$-_.+!*'()," [not including the quotes - ed], and reserved characters used for their reserved purposes may be used unencoded within a URL.
