Admin notification email doesnt work UTF8 problem

Dear Developer,

Great plugin, i only found 2 problems:
1. I didn’t get notifications whenever new users sign up. i checked with 2 different active email addresses.

2. UTF-8 Characters (for example: hebrew) are not shown in the emails – instead it looks like gibberish, something like: @#$@#

any help would be appreciated!
