String encoding - German umlaut

问题

Using C#, Framework 4.0, I'm facing a tricky problem with the german language.

Considering this snippet :

string l_stest = "ZÄHLWERKE";
Console.WriteLine(l_stest.Length); // 9
Console.WriteLine(toto.LengthInTextElements); // 9
Console.ReadLine();

The result will be 9;

Now, selecting the text withing Notepad++, it will give me a length of 10.

I'm guessing the encoding is the source of my problem but without having to scan my words and replace the Umlauts by the matching two letters (Ä -> AE), how can I proceed to calculate precisely the length of my strings ?

Edit : I consider the correct length is 10.

Thanks in advance !

Encoding.UTF8.GetByteCount(l_stest) looks like it'll get the length you want.
