I am having the very same problem, and I have checked my wp-config file (new installation of WP 2.5), and it does not have those two lines. I have seen other posts recommending deleting these two lines, but if they are not there, and one is having the exact same problem with Japanese turning to question marks, and one’s settings are set to UTF-8, how can the problem be resolved? I am entering the Japanese both directly into the post window, and pasting it in from another program like MS Word or notebook, all with the same results.
Thanks.
