Java PDFBOX text encoding
提问by javment
I try to export some data from my Java application to a pdf file. I decided to use the pdfBox library,but I realized that I could not do the Greek characters displayed properly into the pdf file. Is there a way to set the encoding? to utf8, or iso-8859-7? I try something like PdFontEncoding or Encoding but I did not get anything.

Thank you for your time.
感谢您的时间。

There are two things you would need to do:
您需要做两件事：
- set the encoding, and
- provide a font with Greek characters
- 设置编码，和
- 提供带有希腊字符的字体
The inbuilt fonts that most PDF readers have (ie Adobe Reader, OS X Preview, etc) only have the latin1encoding, which doesn't include Greek characters. See http://libharu.sourceforge.net/fonts.html
大多数 PDF 阅读器的内置字体（即 Adobe Reader、OS X Preview 等）只有latin1编码，不包括希腊字符。见http://libharu.sourceforge.net/fonts.html
My guess is that problem here is not with the encoding, instead the problem is the font. You will need to obtain a font with Greek characters and embed it in the PDF file. Make sure you have a licence to embed the font!
我的猜测是这里的问题不在于编码，而在于字体。您将需要获得带有希腊字符的字体并将其嵌入 PDF 文件中。确保您拥有嵌入字体的许可证！
