HI There,

I have the latest WP 4.3.1. On it, I have cost-calculator plugin in my site and I am facing similar issue with äö characters than in ticket: #31566 ( in Thunderbird and Roundcube emails)

I didn't quite understood how to solve this problem. What should I now do to fix this problem?. my client have one of those emails systems that get bad messages from their site.

The plugin provider says they have not use anything special apart from built it WP api.
Plugin provider mentioned that this issue was suppose to be fixed from WP 4.2+/

Any help would be nice.
