iText libs - 不显示西里尔文（俄文）符号
我已经度过了几天，我做错了什么？我只是不能把俄罗斯人物拿出来。尝试了上面的所有代码 - 它没有帮助。下面我用不同的选项引用我的代码。请帮帮我。
图书馆连接如下

答案 0 :(得分：1)
对于iText 7：
Document doc = new Document(new PdfDocument(new PdfWriter("output.pdf")));
String FONT_FILENAME = "./src/main/resources/arial.ttf";
PdfFont font = PdfFontFactory.createFont(FONT_FILENAME, PdfEncodings.IDENTITY_H);
doc.setFont(font);
// Font can be applied to other elements, e.g.
// new Paragraph("Some text").setFont(font);
// new Table().setFont(font);
其中arial.ttf是字体文件（要下载/复制）。

最后。我得出一个变体如何推导俄罗斯符号。
文件|新的|文件夹|资产文件夹 创建新文件夹/字体
我们复制文件arial.ttf或times.ttf，我们粘贴到创建的文件夹/ assets / fonts
在项目中我们写下以下内容：
public static final String FONT = "/assets/fonts/arial.ttf";
BaseFont bf=BaseFont.createFont(FONT, BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
Font font=new Font(bf,30,Font.NORMAL);
document.open();
document.add(new Paragraph("Привет",font));
document.close();
所有这些都是关于欢呼的 Спасибовсемктонепомог:) Подробнееоактивахнасайтеhttp://developer.alexanderklimov.ru/android/theory/assets.php
