Php – HTML – form field is not sent when containing special characters

Firefox 30 ignores autocomplete="off" for passwords, opting to prompt the user instead whether the password should be stored on the client. Note the following commentary from May 5, 2014:

• The password manager always prompts if it wants to save a password. Passwords are not saved without permission from the user.
• We are the third browser to implement this change, after IE and Chrome.

According to the Mozilla Developer Network documentation, the Boolean form element attribute autocomplete prevents form data from being cached in older browsers.

<input type="text" name="foo" autocomplete="off" />

Have your Rails application set the Content-type header, and then you won't need to worry about what Apache is doing.

response.headers['Content-type'] = 'text/html; charset=utf-8'

You may also want to add

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

to the page itself, so that if someone saves it to disk, it will load with the correct charset.
