I'm trying to store the emails which have some special characters but either craftcms or yii tries to encode the strings, this is OK with Vanilla PHP
Also, I put a log in src/controllers/UsersController.php:1022 to get the $_POST to see posted data and still was encoded.
I鈥檓 not seeing any issues saving a user account with the email aaa@盲枚.ee. Can you be more specific as to what you are entering and where it is getting encoded?
I tested with the front sign-up form, not admin and the username filled automatically by CraftCMS and is encoded. @brandonkelly
Got it, thanks. We鈥檝e fixed this for the next release.
Craft 3.5.16 is out now with that fix.
