How to convert javascript strings to utf-8 encoding

This article will explain in detail how to convert javascript strings into utf-8 coding. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

1. Support for window.TextEncoder ()

Function str2utf8 (str) {encoder = new TextEncoder ('utf8'); return encoder.encode (str);}

This returns an array of integers.

2. Replace with the code of encodeURI

The principle is that if you use encodeURI (str), if you encounter Chinese characters and so on, it will become% E5% 91 after utf8 encoding. We use this, and then replace% with\ x, and get a single byte string.

Function str2utf8 (str) {return eval ('\'+ encodeURI (str). Replace (/% / gm,'\\ x') +'\');} this is the end of the article on "how to convert javascript strings into utf-8 coding".
