For any data file it raises Uncode error

For any dataset even for the given ones, the File widget reports this error.

I tried my csv file and adult.tab and car.tab datasets. Result is always same

UnicodeDecodeError Traceback (most recent call last):

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 2: ordinal not in range(128)

Start with Orange/OrangeWidgets/OWWidget.py at reportAndFinish and Orange/OrangeWidgets/OWReport.py at appendReport and addEntry. Reproduce the failure through the File widget using the reported CSV, adult.tab, or car.tab datasets, then verify that generating the report completes without the UnicodeDecodeError.
