Base64 encoding btoa












1















I am encoding some text on my frontend part using btoa function:



const encodedText = btoa(searchText);


This seems to work totally fine and decoding goes like this on backend part:



byte decodedBytes = Base64.getDecoder().decode(searchedText);

String decodedString = new String(decodedBytes, Charset.defaultCharset());


Which also works fine. However, this seems to fail when using ü letter. My program encodes it as A==, and as far as I know, it should be w7w=



I am not sure what I did wrong.






java angular encoding

          You could use



          const encodedText = btoa(unescape(encodeURIComponent(searchText)));


          instead to encode unicode characters first.



          See Unicode strings and The "Unicode Problem" for further reading.






          console.log(btoa('ü'));
          
console.log(btoa(unescape(encodeURIComponent('ü'))));

          • apparently it was enough to use encodeURIComponent(btoa(searchText))
