Overview

If you're sending emails that contain a foreign language, it's likely that you're using special characters that may not render correctly in the email inbox.

For example:

Olá Mundo

May render in the inbox as:

Olá Mundo

Solution

1. Convert all special characters to HTML entities.  You can use an HTML Character Converter such as provided by Email on Acid.

For example:

Olá Mundo

Should be converted to:

Olá Mundo

2. Alternatively you can add the following code to the first line of your HTML document:

<?xml encoding="utf-8" ?>
