If you mean %23, don't write it as '#'. The %-enc should be retained, and matched distinctly, unless their plaintext is equivalent, e.g. meets none of the sub-delim or delim or restricted set. Which must therefore include %25, % encoded '%' itself. Any %41 or 'A' are equivalent because their definition is an identity. But I don't know that you can use %41 in the match pattern as we would not decode that, and you likely can force any result to contain a %41. This is not well handled in general, there are ideas floating around, but since there is no committee interest beyond 2.4.x and complete division of opinion on how anything >2.4.x would be managed, it looks most practical to clearly document existing observed behavior.
