Are you sure that pr-str produced that string? %20 is a space urlencoded which
looks like you are urlencoding the value you get from pr-str. Not sure that
will work, but even if it does its far from ideal since basically every literal
has to be urlencoded.
How are you transporting the strings from client -> server, most clients
default to content type "application/x-www-form-urlencoded". What you want to
do is transport the data as is as either text/plain or application/edn,
urlencoding is not a suitable transport encoding (IMHO).
Can't say more without actual code references.
Anyways, HTH.
