I believe it was options-reading.php.
I remember I was looking to adjust coding for RSS feed.
I first applied UTF-4, with no difference. Followed by UTF-16 which is where the problem occured. I read through the code and believe the function blog_charset is what set it; whether it was to another PHP page/function or to the database is beyond me.
I’ve considered backing up the database (something I have to ask the school to do for me) and rolling in the new update manually and hoping it’ll be a fresh start, using the same database. But, if it’s posted that to the database, then the problem will remain in a fresh version.
Thank you for your reply as well as in advance for your time.
