>From Randy H:

I had similar issue with the latest jexl 1.1 release. Seems the option for
unicode support is not enabled when using the parser was generated.

Here is what I did to get it work with non-ASCII code:

1. Download and unzip jexl 1.1 source from:
http://www.axint.net/apache/jakarta/commons/jexl/source/commons-jexl-1.1-src.zip

2. Download and unzip JavaCC 4.0 from:
https://javacc.dev.java.net/files/documents/17/26777/javacc-4.0.zip

3. Run javacc-4.0\bin\javacc -UNICODE_INPUT
commons-jexl-1.1-src\src\java\org\apache\commons\jexl\parser\Parser.jj

4. Copy *.java to
commons-jexl-1.1-src\src\java\org\apache\commons\jexl\parser

5. Run ant -f commons-jexl-1.1-src\build.xml

6. Use the new jar commons-jexl-1.1-src\target\commons-jexl-1.1.jar

7. Profilt! :)
