ruby-watir view coding format

watir see whether the text in the value of certain coding?

ie.div (: id, 'alertbox-con'). p (: index, 0). text.force_encoding ("UTF-8"). valid_encoding?

Or

ie.div (: id, 'alertbox-con'). p (: index, 0). text.force_encoding ("GBK"). valid_encoding?

If it returns true, returns false

Another method is more simple to query whether a particular encoding:

ie.div (: id, 'alertbox-con'). p (: index, 0). text.encoding

Return should be coded format
