Note: mb_strwidth is NOT returning bytes.  It's returning the width of monotype characters.  (In some languages, some characters will take up 2 character widths if displayed in monotype.)

Important, if you're looking to trim/cut/truncate a string so that it will fit a certain byte size (for example to fit in a database field), look at:  mb_strcut()
