To display multi-byte characters (i.e Japanese, Korean and etc) in WordPress, I've done the required steps below and the mult-byte characters are displayed properly.
However, the dashes, quotes, apostrophes and etc have turned into black diamond question marks on the pages.
1. Commenting out these two lines in wp-config.php
2. The "latin1_swedish_ci" is replaced with "utf8_general_ci" the Collation field for every table in the database.
3. Settings -> Reading -> Encoding is set to UTF-8
Besides the above three steps, what else should I change to fix the question marks? Thanks.
