大虾Prawnto Rails PDF生成-UTF-8? [英] Prawn & Prawnto Rails PDF generation - UTF-8?

问题描述

我正在使用ruby，prawn和prawnto动态生成包含其他语言的pdf文本.我似乎看不到任何带有非英语字符的语言文字.它不会引发任何错误...只是显示一堆破折号而不是字符.大虾在其主页上吹嘘关于UTF-8支持，因此我不明白为什么这是个问题.我正在使用ruby 1.8.6(engineyard).

I'm using ruby, prawn, and prawnto to dynamically generate pdf's containing text in other languages. I can't seem to get any text in languages with non-english characters to show up. It doesn't throw any errors...just shows a bunch of dashes instead of characters. Prawn brags on its homepage about UTF-8 support so I don't see why this is a problem. I'm using ruby 1.8.6 (engineyard).

推荐答案

要使Unicode正常工作，您需要加载包含所需字符的TTF字体.

For Unicode to work you need to load a TTF font that has the characters you require.

默认的Helvetica字体仅支持ASCII(加上一些附加功能).

The default Helvetica font only supports ASCII (plus a few extras).
