This is file when i got error
wycena_polis_2016-11-16 11-27.xls.zip

[lhcGinv]

this is my promble too:
iconv(): Detected an illegal character in input string
ConvertEncoding('商品分类demo', 'UTF-8', 'CP1252')

[lhcGinv]

To avoid this error,the first row must use utf-8 code in my excel file

seems like autodetect is not the same name as its in iconv. (MACCENTRALEUROPE vs MAC-CENTRALEUROPE)

what helped me is this:

// composer.json
    "autoload": {
...
        "files": ["override/StringHelper.php"]
    },

copy builtin StringHelper to your override/StringHelper.php location, and add the following "hack":

public static function convertEncoding($value, $to, $from)
    {
        if($from === "MACCENTRALEUROPE"){$from = "MAC-CENTRALEUROPE";} //patched
        if($from === "MACCYRILLIC"){$from = "MAC-CYRILLIC";} //patched
        if (self::getIsIconvEnabled()) {
            $result = iconv($from, $to . self::$iconvOptions, $value);
            if (false !== $result) {
                return $result;
            }
        }

        return mb_convert_encoding($value, $to, $from);
    }

(edit: i can see that there were a fix for this, so if you can, use that :) )
