URL grammar rules

I made a pastebin site where each entry gets a random string. For example

example.com/ds34
example.com/sdf-2zA
example.com/234+_2

My question is, what is the grammar rule for these strings? Can that start with anything? which characters are/aren't allowed?

See in RFC and w3.org. In short - any ASCII symbol excluding reserved ! * ' ( ) ; : @ & = + $, / ? % # [ ]. Other symbols can be percent-encoded.
