`char.MaxValue` in C# is 65535, so `var high = c >> 8;` in source code cannot exceed 255, while character file has values ranging from 468 to 497. It is incorrect to loop through individual characters of input, `EnumerateRunes()` must be used instead. Reproduction: ```cs // p.csx #r "nuget: Unidecode.NET, 2.1.0" using Unidecode.NET; var a = "更".Unidecode(); // f901 Kayng var b = "🄁".Unidecode(); // 1f101 0, Console.WriteLine(a); Console.WriteLine(b); ``` ```ps dotnet script p.csx ``` Outputs: Kayng
