Hello!
I had an issue with the characters in the registration e-mail and found that the encoding is set to ISO-8859-1. I wonder why, having in mind that today the whole world uses UTF-8.
Then found that someone else had similar issue.

I just want to suggest to change it to UTF-8 in the new version.
Kind regards,
