With my move today, I was getting all these funky  characters all over the place. Always seemed to be just before a double space, so that lead me to believe that somehow the encoding was wrong.
Turns out the default config file has some encoding options turned on by default that was causing the problem. I was able to resolve it by commenting them out as follows:
/** 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’, ”);
Fixed all those funky  that had suddenly appeared!
