Here's a solution that applies this answer to your code.
public static void Main()
{
var nameLv = "Jevģeņijs";
var nameEng = "Jevgenijs";
var result = IsEquivalent(nameLv, nameEng); // returns True
}
public static bool IsEquivalent(string latvian, string english)
{
return english ==
Encoding.UTF8.GetString(Encoding.GetEncoding("ISO-8859-8").GetBytes(latvian));
}
I can't say whether this is the most robust method or will work given any particular strings, but tested with your input it seems to work fine.
There are quite a few other solutions in that same thread that you might want to check out too.
