It is unsafe to write confidential text in a web browser since JavaScript attacks can access it from inside the browser. You should rather write your text in a separate application, encrypt it using OpenPGP Applet, and paste the encrypted text in your browser, before sending it by email for example.

When using OpenPGP Applet to encrypt emails, non-ASCII characters (for example non-Latin characters or characters with accents) might not display correctly to the recipients of the email.
