Strange characters appearing in wordpress

问题:

I'm having a niggling wordpress problem

Whenever i'm adding an Apostrophe to a wordpress post I create

'

Its saving as a strange set of characters

’

I've used wordpress many times, never encountered this problem

I've uninstalled every single plugin, and the problem remains

I read somewhere to comment out these lines in wp-config.php but it doesn't help for new posts

/** Database Charset to use in creating database tables. */
//define('DB_CHARSET', 'utf8');

/** The Database Collate type. Don't change this if in doubt. */
//define('DB_COLLATE', '');

Can someone help me? DO need to set the Charset to override somewhere? How??

I have to update the thread, as follows. I followed just about every tutorial out there addressing utf-8 mismatch, nothing helped Finally we spotted some phishing code had been injected into the root index file (also linked to some 3rd party adult site, but our site was not redirecting , Needless to say, we cleaned that up Many thanks for everyone for helping, especially @user850010 I hope This thread will be useful for others

If that strange character is stored in DB, then it seems that your DB is not set up with the UTF8 charset, so you can uncomment those 2 lines in wp-config.php, since they are not the source of the problem.

You have a comprehensive tutorial how to convert Character Sets with WordPress Database but here is the short list what to do:

• Make a backup of your DB

• Maybe it would be better make a copy of your site on your local computer and try the below changes there

• Convert DB (this will not affect existing tables, just those future new created tables)

  ALTER DATABASE MyDb CHARACTER SET utf8;

• convert any tables in the database that are not already in the desired format.

  Focus on the tables wp_posts and wp_postmeta

  ALTER TABLE wp_posts CHARACTER SET utf8

  ALTER TABLE wp_postmeta CHARACTER SET utf8

• individually alter each column of each table to use the correct the character set. This is not a simple process, read carefully the section of above link regarding columns.

Run this query:

ALTER DATABASE MyDb CHARACTER SET utf8;

After edit wp_config.php and set:

define('DB_CHARSET', 'utf8');
