Input file should be in UTF-8

[krandma]

Greetings from Erply! We are delighted that you have shared this work on GitHub.

One note: Erply API expects all input encoded in UTF-8. Your attached sample file is in latin-1 (or Windows-1252, or similar one-byte encoding), as far as I see, that is why it did not import.

So either the sample file should be converted to UTF-8 (instructing others to do the same with their input files), or the script should include a conversion routine eg.
utf8_encode($str)
or
mb_convert_encoding($str, "UTF-8", "Windows-1252");

Best regards,
Kristjan Randma
