Question

GB2312如何转UTF-8？使用对照表还是有算法？

Answer 1

'GB2312的字节'.decode('gb2312').encode('utf-8')

Answer 2

看各个平台，一般都有现成的库,我最近用的 平台是react-native
库名iconv
`const getBookChapter = function(chapter, book) {
return new Promise((resolve, reject) => {

axios({
  method: 'get',
  url: chapter.url,
  responseType: 'arraybuffer'
}).then(res => {
  let dom = iconv.decode(new Buffer(res.data), book.source.encoding)
  resolve(catchBookChapterContent(dom, book.source))
})

})
}`
