Error occurs when scanning a folder or filename containing special characters character

[josemoliver]

If a folder contains a special character, for emaple "é" or "á". The scan abruptly terminates and the following error message appears:

[EXCEPTION] - The input does not contain any JSON tokens. Expected the input to start with a valid JSON token, when isFinalBlock is true. LineNumber: 0 | BytePositionInLine: 0.

The problem occurs in ExifToolHelper.cs, which has problems with the Windows character encoding. Even specifying StandardOutputEncoding = Encoding.UTF8 it seems to fail.
