Is it possible to use literal %2F inside a dovecot.http.client request url?

Hello,

I'm using dovecot (2.3) lua with dovecot.http.client but I need the request url to have an url encoded slash (/) as %2F (or %2f) but if I enter for example https://test.com/%2F/test it looks like it changes it to a slash (https://test.com///test) in the http debug log (also the request fails as it's not %2F).

I've also tried with %252F to encode the % but that doesn't change at all (keeps being %252F) & also tried with %%2F and \%2F but that gets the errors "Expecting hex digit after '%', but found '%'" for %%2F and "invalid escape sequence" for \%2F.

Does anyone have an idea how to solve this or if it's even possible?
