Is there a query string character whose value "ignores the string outside this point"?

Question

Is there a reserved query string character that is commonly used to ignore sections of a string? Something like that:

?foo=bar&baz=quux*some character*&sky=blue 

If adding a character results in this query string ignoring the end:

 ?foo=bar&baz=quux 

I know that it is usually for programs analyzing the query string to decide how something is processed, but I wanted to know if something like this exists, just like the + symbol denotes space.

Answer 1

The fragment identifier indicated by # has the effect :

The query component is indicated by the first question mark (" ? ") And ends with a number sign (" # ") or towards the end of the URI.
