Java PDF文档中未出现土耳其语字符(PDFGS2D)
下面的代码是打印为PDF的Java2D应用程序的简化示例。它如何不打印“使用” 输出是这样的 问题是如何将这些字符打印到PDFGraphics2D。用于创建PDF的java代码正常工作。代码在这里供快速参考Java PDF文档中未出现土耳其语字符(PDFGS2D),java,rendering,itext,Java,Rendering,Itext,下面的代码是打印为PDF的Java2D应用程序的简化示例。它如何不打印“使用” 输出是这样的 问题是如何将这些字符打印到PDFGraphics2D。用于创建PDF的java代码正常工作。代码在这里供快速参考 import com.lowagie.text.Chunk; import com.lowagie.text.Document; import com.lowagie.text.DocumentException; import com.lowagie.text.Font; import

问题出在mapper上。它的
awtToPdf()/pdf2awt()
应该设置为返回正确的字体
固定代码,仅供参考。。(映射器的实际设置更为复杂)
