You need to read the file using the Encoding that the file is written in.

It appears to be a non Unicode file that you are trying to read as Unicode, or possibly a different Unicode encoding than the default UTF-8 (could be UTF-16 for example).

StreamWriter has several constructors that the an Encoding as parameter.

You can do it by validating each character in the string against the 128 characters in the ASCII table. If the character is not found there then it might be a unicode character.

Is that what you mean?
