c# - "ISO-8859-1" Encoding in javascript -


i've created base64 encoding string in following format using c#. want create same encoded string using javascript. 

var isoencoding = system.text.encoding.getencoding("iso-8859-1"); var = isoencoding.getbytes(username + ":" + password); string encoded = system.convert.tobase64string(a); request.headers.add("authorization", "basic " + encoded);

here used iconv , try encoded string , gives differen encoded string. can reason? 

var str  = this.username+':'+this.password; var s = iconv.encode(str, 'iso-8859-1'); var = btoa(s.tostring());  headers.append('authorization', 'basic ' + a);

use instead of btoa:

var = s.tostring('base64');

the default encoding buffer.tostring utf-8
