Enable Spell Checker Available in all Editions. If this option is selected, the Check Spelling button appears in certain areas of the application where text is entered, such as sending an email, or when creating events, tasks, cases, notes, and solutions. Clicking the button checks the spelling of your text. Spell Checker does not support all the languages that Salesforce supports. For example, Spell Checker doesn’t support Thai, Russian, and double-byte languages, such as Japanese, Korean, or Chinese.
