<div>Don, <br>there is no such thing as IDN at .RU - only ascii allowed - we understood the problem long time ago due to similarity of many Cyrillic letters with Latin. </div>
In IDN .РФ in Russia only Cyrillic allowed. <br>This definitely must be the rule for registries. Or some kind of immediate mitigation service to bring down dangerous domains. <br><br></div>

<div>Hello Don, <br><br>Which all registries are allowed to register mix of scripts domain while registering an IDN. I checked .pyc (Cyrillic) and .भारत (Devanagiri) do not allow mix of scripts. I think we address those registries through ICANN by modifying the registry agreement, major problem can be solved. <br><br>Thanks. </div>

However, you may have noticed a renewed focus over the past week of a script mixing technique that phishing scammers could potentially use to trick Internet users into visiting malicious websites. This phishing method takes advantage of the fact that characters from various languages and scripts are sometimes visually similar to each other. For example, the Cyrillic “</span><span style="font-size:11.0pt" lang="RU">а</span><span style="font-size:11.0pt">” and the <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__en.wikipedia.org_wiki_ASCII&d=DwMFaQ&c=FmY1u3PJp6wrcrwll3mSVzgfkbPSS6sJms7xcl4I5cM&r=YI0XKyKCabKQi3GVWLvuoyCWjH9WBgEBxLbMnmhSRwo&m=b2_5n2l3R5eXR7olCx9BY0h-_Kk-odvJXTKIexpQvuM&s=yfwSeTzAiHcLTq4jEae3TOx116_t2m_mn8vT4UOo7Go&e=" target="_blank">ASCII[en.wikipedia.org]</a> “a” look virtually identical.

IDNs are essential in bringing non-English speakers – the majority of the world’s population – online, and allowing those users to create their own highly relevant online identities as well as navigate the Internet in their native languages. In addition to the social and cultural benefits of IDNs, they also represent a significant economic opportunity; a recent <a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__uasg.tech_whitepaper_&d=DwMFaQ&c=FmY1u3PJp6wrcrwll3mSVzgfkbPSS6sJms7xcl4I5cM&r=YI0XKyKCabKQi3GVWLvuoyCWjH9WBgEBxLbMnmhSRwo&m=b2_5n2l3R5eXR7olCx9BY0h-_Kk-odvJXTKIexpQvuM&s=VMxJkqVb1W-ZyIEhQREIQRg3LsygAashMrgpllm7Qs4&e=" target="_blank">report[uasg.tech]</a> commissioned by the Universal Acceptance Steering Group (UASG) found that online spending from new IDN users could start at USD 6.2 billion per year. </span></p>
