Describe the Bug

When trying to load a dynamic url like alphabet/:letter.astro if the letter includes or is equal to %23 i get the error:

Expected "letter" to match "[^\/#\?]+?", but got "#"

What's the expected result?

I expect the page to load with the param resolving to either # or %23.

I think this is a duplicate of #8516

[Elias-Chairi]

I am sorry, i might have explained it poorly. The example in #8516 is with paths generated with the getStaticPaths method in static or hybrid mode. My problem is with a path in ssr mode. The example path used in the other issue seems to work fine in a dynamic path in ssr mode.
