If you're creating Form using Vibe shortcodes plugin and the language you use require you to send emails in languages which are in ISO charset.

You simply need to generate the form shortcode and add an additional parameter in the [form shortcode : isocharset=1

Below an example of generated shortcode :

Code:

[form to="example@example.com" subject="Subject" isocharset=1] [form_element type="text" validate="" options="" placeholder="Name"] [form_element type="text" validate="email" options="" placeholder="Email"] [form_element type="textarea" validate="" options="" placeholder="Message"] [form_element type="submit" validate="" options="" placeholder="Submit"] [/form]

Note the isocharset parameter added in the form shortcode.
