Re: Format of export data (ISO-8859-1 or UTF-8)

The auto-detection of file encoding for uploaded files is based on a heuristic analysis of a sample taken from the first 64k of the file. Whilst this is effective for differentiating between, say, big- and little-endian UTF-16, it can can produce varying results for encodings that share most common code units, depending on the contents of that first 64k. As Alex suggests, knowing what encoding a text file is in and checking it is correct on upload is the best policy for trouble-free imports.
