set_prolog_flag(double_quotes, chars). not having effect

I am using Ciao prolog version 1.15.

I tried

?- set_prolog_flag(double_quotes, chars).

yes

?- current_prolog_flag(double_quotes,X).

X = chars ?

yes

?- X = "hello".

X = [104,101,108,108,111] ?

so it seems like setting this flag is not working because the codes are returned rather than characters, even though the flag is set. Any ideas?

Same problem in Ciao 1.22.0. Also, trying to set the flag to either `codes` or `atom` fails. – Paulo Moura Apr 28 '23 at 09:08
