关于c＃：ToLower vs ToLowerInvariant

ToLower vs ToLowerInvariant

我只是在寻找这两种方法产生不同结果的任何例子。首先，我访问了msdn页面，运行其中的代码，并做了一些小的更改。

using System;
using System.Globalization;
using System.Linq;

class Program
{
static void Main()
{
string[] words = {"Tuesday","Sal?","Вторник","Mardi",
"Τρ?τη","Martes","??? ?????",
"????????","?????????" };
Console.BufferHeight = 1000;
var test = CultureInfo.GetCultures(CultureTypes.AllCultures)
.Select(ci =>
{
string[] wordsToLower = words.Select(x => x.ToLower(ci)).ToArray();
string[] wordsToLowerInvariant = words.Select(x => x.ToLowerInvariant()).ToArray();
return new
{
Culture = ci,
ToLowerDiffers = !wordsToLower.SequenceEqual(wordsToLowerInvariant)
};
})
.ToArray();
foreach (var x in test)
{
Console.WriteLine("Culture {0}, ToLower and ToLowerInvariant produces different results: {1}", x.Culture, x.ToLowerDiffers);
}
Console.WriteLine();
Console.WriteLine("Difference exists for any ToLower call: {0}", test.Any(x => x.ToLowerDiffers));
}
}

但这里我有一个问题：这个代码为所有现有文化中的ToLower和ToLowerInvariant调用生成相同的输出。

所以问题是：有任何字符串可以为这个测试产生不同的结果吗？
