Not sure I am doing exactly what you suggest but the following (based
on your suggestion) seems to work:
(define auth "Marjanović+Ž")
(http-request (string-append "https://......&term="; auth
"[auth]&retmax=20")) ===> error!!
Throw to key `encoding-error' with args `("put-char" "conversion to
port encoding failed" 84 #<input-output: string 7f9a247d75b0> #\ć)'.
(define authencode (uri-encode "Marjanović+Ž")) ===>
"Marjanovi%C4%87%2B%C5%BD"
(http-request (string-append "https://....&term="; authencode
"[auth]&retmax=20")) ===>success!!
Thanks
