这在显示的 pdf 中仅显示英文字符。而印地文字体是不可见的。
我用印地语输入的内容也会在文本区域中以印地语检索。但在 pdf 上我无法以印地语检索它。
我应该怎么做才能用印地语检索它？
最佳答案
即使是最新的 iText 版本也有可能不支持梵文脚本，引用 here .
但是，还有其他选择，例如使用 awt Graphics2D 类、设置支持 unicode 字符的字体并将其添加到 PDF(但不是文本)。
示例:here
使用上述引用的输出:
“印地语中的新 PDF”在此处呈现为文本
关于java - 让印地语显示在使用 JSP 创建的 pdf 上，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20966185/
