Two string value are the same but CompareTo doesn't return 0

I create wpf application. And some case I compare two string values. local value comes from richtextbox, and richtextbox value comes from word document. I try every solution on this site. But nothing changed. The comparision equal to false. I try replace end of file with linkedWord.Replace((char)160, (char)32);

Try string.Compare

String.Compare(wr.Orthography, linkedWord, StringComparison.OrdinalIgnoreCase) == 0

Use Encoding to byte array and SequanceEqual and more, but can not find solution. Please help me to solve this problem.

The value comes from richtextbox: enter image description here

the value comes from database:

EDIT:

After Compare method result is -1

The reason is probably that cyrillic ә(ә) and latin ə(ə) are different though they look same.

Check each character for equality, below you can see the difference:

foreach (char c in "bәse")
    Console.Write(((int)c).ToString("0000"));

Console.WriteLine("\n--------------------");

foreach (char c in "bəse")
    Console.Write(((int)c).ToString("0000"));

Console.WriteLine("\n--------------------");

Console.WriteLine(("bәse"=="bəse").ToString());

Output

0098124101150101
--------------------
0098060101150101
--------------------
False

DOTNETFIDDLE

In this case you should replace the cyrillic chars with latin counterparts

You can see here and also check here, it seems like there is a library that can be used in this case
