That is the Hebrew (ISO-Visual) encoding. Standardization of datasets is a common requirement for many machine learning estimators implemented in scikit-learn; they might behave badly if the individual features do not more or less look like standard normally distributed data: Gaussian with zero mean and unit variance. I have ten CSV files and I would like to combine them to one ods file comprised of ten sheets, one per original CSV. Hi Marcelo, It's not a problem with Collect but it's a problem with Excel: the generated CSV file uses a UTF-8 character encoding, but Excel tries to read it using a different encoding (probably ISO-8859-1) and does not give the possibility to choose a different one.
