Jasper Unicode问题与字段参考有关，但与资源包参考无关

[英]Jasper Unicode issue with Field Reference but not Resource Bundle Reference

原文 2013-07-02 16:25:55 8 1 java/ unicode/ jasper-reports/ pdf-generation

I am using Jasper Reports to produce PDF reports. 我正在使用Jasper Reports生成PDF报告。 When I have diacriticals in resources ($R expressions), they display fine, but when (in the same report, even in the same TextField element, just swapping the innermost expression) I have Field Reference ($F expression), the diacritical mark is not displayed. 当我在资源中使用变音符（$ R表达式）时，它们显示的很好，但是当（在同一报表中，即使在相同的TextField元素中，只是交换最里面的表达式）我有了字段引用（$ F表达式）时，变音符不显示。 "Mĕdical" comes out as "Mdical". “医疗”以“医疗”的形式出现。

It can't be font or style (because with the identical font and style, $R expressions display the diacritical without problems). 它不能是字体或样式（因为相同的字体和样式，$ R表达式显示变音符没有问题）。 It can't be encoding (UTF-8, although I've also tried others) for the same reason. 出于相同的原因，它不能进行编码（UTF-8，尽管我也尝试过其他编码）。

I've stepped into the code in the debugger and I know without question that the string being returned to Jasper Reports contains the diacritical character. 我进入了调试器中的代码，毫无疑问，我知道返回给Jasper Reports的字符串包含变音字符。 What could be causing this problem and where can I look to find it? 是什么导致此问题，我在哪里可以找到它？

1 个解决方案

This turned out to be a two-part problem. 原来这是一个两部分的问题。

I was using a different diacritical character in the $F expression from the $R expression, and the $F diacritical was not supported by my font. 我在$ F表达式中使用的变音符与$ R表达式不同，并且我的字体不支持$ F变音符。
I was HTML-escaping the string that fed to Jasper Reports, and I needed to XML-escape it instead. 我正在用HTML转义提供给Jasper Reports的字符串，而我需要XML转义它。
