ESP32 programming error

Why this error?

UnicodeEncodeError: 'gbk' codec can't encode character u'\xf5' in position 13: i
llegal multibyte sequence

Unfortunately I don't have visibility into Espressif's tool. However using google to lookup 'gbk' (https://pub.dev/packages/gbk_codec) and this error leads me to believe that the tool doesn't like the encoding in some string. There is some unicode it can't understand. Perhaps one of the filename strings has the extra unicode. Is there another way you can enter these strings?
