Reading through that RFC, I note the following paragraph:
2.3. Unreserved Characters
Characters that are allowed in a URI but do not have a reserved
purpose are called unreserved. These include uppercase and lowercase
letters, decimal digits, hyphen, period, underscore, and tilde.
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
To me, this quite clearly states that underscores ARE permitted in URLs. Any
code that fails to allow them is contrary to the RFC.

That's about a colon, not an underscore.
