推荐答案

那是javaScript，您必须对Unicode字符使用\u转义.

That's javaScript, you have to use \u escapes for Unicode characters.

$scope.somePlaceholder = '\u25cf\u25cf';

或者只是按字面写这些点(假设脚本的编码已由Web服务器正确声明).

Or just write those dots literally (assuming the encoding of your script is declared properly by your web server).

$scope.somePlaceholder = '●●';
