I just upgraded the blog from a recent version to 2.8.4.
The blog, which has Japanese and English text, became COMPLETELY mangled as a result of the upgrade as is seen here:
After searching on these forums, I used PhpMyAdmin to convert all the tables from latin1_swedish to ut8_unicode_ci.
After the conversion, nothing has changed...I still have a weblog filled with mangled Japanese text, despite the fact that both the MySql tables and the wordpress installation are ostensibly configured for Unicode.
Any thoughts on what I can possibly do now to get the Japanese back into readable form? Restoring the Mysql database from before the upgrade and upgrading it again did not work wither.
I hope that someone will have suggestions for me!
