Bypassing the block of Security Domain Restriction and normally invite blocked domains with special characters “İ”

## Summary: Hey sub, Hope you are doing well today inshallah <3 I found a bug that allows the users to invite someone with a blocked domain in the project .. If the owner for example made a rule that no one can invite emails of `yopmail.com` I would be able to invite them normally and break his rules with special charachters .. We gonna use “İ” instead of “I” or “i” ## Steps to reproduce: 1. There sould be a rule at first blocking the domain for example `yopmail.com`, add it from: **Settings ⇒ Security ⇒ Domain Restrictions ⇒ Deny Only ⇒ and add** `yopmail.com` 2. Go into your inviting dashboard from: **Settings ⇒ Users ⇒ Invite Users** 3. If we tried to invite someone now with the blocked domain, We gonna get error saying: {F2432936} 4. Now Let’s Invite “email@yopmaİl.com” instead of “[email protected]” 5. Here we go, It’s invited successfully: {F2432937} 6. and I receive a message of inviation on the email normally: {F2432938} 7. Thank You <3 ## Note: - You can use this backup for more special chars: https://0xacb.com/normalization_table ## Impact - Breaking the owner’s rules and inviting a blocked domain to the project - rules violation
