java - 如何在 Jasper PDF 报告中呈现 Bangla SolaimanLipi 字体

Question

我们正在使用 Jasper 报告 4.x。在 jasperreports-fonts-4.5.0 上嵌入字体后，它可以在 Jasper Viewer 中使用 Unicode 字符集(如阿拉伯语、Bangla 和 SolaimanLipi)正常工作。但是当我尝试获取 pdf 报告时。 Arabic & English 字体渲染的很好，但是 Bangla 字体没有渲染完全的希望。

这里我使用了 jasperreports_extension.properties

net.sf.jasperreports.extension.registry.factory.simple.font.families=net.sf.jasperreports.engine.fonts.SimpleFontExtensionsRegistryFactory
net.sf.jasperreports.extension.simple.font.families.dejavu=net/sf/jasperreports/fonts/fonts.xml

在 fonts.xml 中做了以下条目

<fontFamily name="SolaimanLipi">
       <normal>net/sf/jasperreports/fonts/rdp/SOLAIMANLIPI.ttf</normal>
       <bold>net/sf/jasperreports/fonts/rdp/SOLAIMANLIPI.ttf</bold>
       <italic>net/sf/jasperreports/fonts/rdp/SOLAIMANLIPI.ttf</italic>
       <boldItalic>net/sf/jasperreports/fonts/rdp/SOLAIMANLIPI.ttf</boldItalic>
       <pdfEncoding>Identity-H</pdfEncoding>
       <pdfEmbedded>true</pdfEmbedded>
</fontFamily>

然后我用自己的字体集重建jar文件

例如它呈现如下:

1. গোপালগঞ্জ而不是গোপালগঞ্জ
2. 用মুন্সীগঞ্জ代替মুন্সীগঞ্জ
3. 用ময়মনসিংহ代替ময়মনসিংহ

我只是像上面那样做了一个虚拟实现。有什么解决办法吗？

Answer 1

我有办法解决这个问题，首先需要使用 Bijoy 编码，然后使用任何 Bijoy unicode 字体 (DestinyMJ)。

গোপালগঞ্জ bijoy编码->†MvcvjMÄ

{NAME_BN} = '†MvcvjMÄ';

它将正确打印গোপালগঞ্জ。
