Why it matters
IDN country extensions let users type full web addresses in their own script. ICANN runs a Fast Track process that lets a country or territory on the ISO 3166-1 list request a string. For buyers, these extensions are a local market play, not a global brand play. Sellers who hold local-script names should expect a narrow buyer pool. Common mistake: assuming an IDN ccTLD works in every app. Email and some software still handle non-Latin addresses poorly, a gap tracked under universal acceptance.
