How can I set my composing language?

You can set the composing language by choosing the language from the drop down box next to the Spell Check Icon. However, you can compose in the language of your choice, if your system and keyboard settings support the language or alternatively, you can compose the mail in a different editor and copy the content here for optimal results. The language selected in the spell checker is used for spell checker purposes. If you want the composer to recognize the fonts properly, you need to choose the correct encoding.
