启用字体子设置时，laravel-dompdf得到错误“未定义索引：glyf”

问题描述

我正在尝试使用pdf库生成laravel-dompdf文件。

这是我使用的字体样式：

        @font-face {
            font-family: 'Hiragino Sans';
            src: url('fonts/Hiragino Sans GB W3.ttf') format('truetype');
            font-weight: normal;
        }
        @font-face {
            font-family: 'Hiragino Sans';
            src: url('fonts/Hiragino Sans GB W6.ttf') format('truetype');
            font-weight: bold;
        }

这是控制器中的代码：

return PDF::loadView('pdf.presaleorder')->save('test.pdf');

一切正常，但是生成的pdf文件太大，大于20MB。我发现可以通过将enable_font_subsetting中的config/dompdf.php字段更改为true来减小它的大小。

但是当我生成pdf文件时，它引发了错误：

 ErrorException  : Undefined index: glyf

当我添加参数-v时，显示了更多的跟踪错误
