Character encoding in XML tag files?

First things first, I'm using Tomcat 5.5.1. I'm moving some code from a 
JSP document to tag files. All of the files are in XML format. The head 
of one of my tag files looks like this

<?xml version="1.0" encoding="ISO-8859-1"?>

<jsp:root version="2.0"
 xmlns:jsp="http://java.sun.com/JSP/Page">

  <jsp:directive.tag pageEncoding="ISO-8859-1" />
  <jsp:directive.tag body-content="empty"/>


I'm precompiling the file with this ant target

  <target name="jspc" depends="prepare">
    <mkdir dir="${build.home}/WEB-INF/src"/>
    <jasper2 
     javaencoding="UTF-8"
     validateXml="false"
     compile="false"
     uriroot="${build.home}" 
     webXmlFragment="${build.home}/WEB-INF/generated_web.xml" 
     addwebxmlmappings="true"
     outputDir="${build.home}/WEB-INF/src" /> 
  </target>

So far, all is working. Problems start, when the file contains 
characters or constants such as 'Ü' and '&#160;'. These result in 
errors like this

An error occurred at line: 47 in the jsp 
file: /WEB-INF/tags/veranstaltung.tagx
Generated servlet error:
Invalid character constant

The tag file is indeed encoded as ISO-8859-1. Alternatively, I tried 
UTF-8, with the declarations changed, too. The result was the same. And 
now for the weird part:

This doesn't compile
<span>Ü</span>

This either
<span>Ü
 </span>

But this does
<span>Ü
  </span>

And so does this
<span>Ü   </span>

So, there have to be 3 whitespace characters after the umlaut to make it 
pass through jasper. =:-O

My normal locale is somewhat involved

LANG=POSIX
LC_CTYPE=de_DE.iso885915@euro
LC_NUMERIC=de_DE.iso885915@euro
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY=de_DE.iso885915@euro
LC_MESSAGES="POSIX"
LC_PAPER=de_DE.iso885915@euro
LC_NAME=de_DE.iso885915@euro
LC_ADDRESS=de_DE.iso885915@euro
LC_TELEPHONE=de_DE.iso885915@euro
LC_MEASUREMENT=de_DE.iso885915@euro
LC_IDENTIFICATION=de_DE.iso885915@euro
LC_ALL=

But I just tried with LANG=de_DE.iso885915@euro and the result was the 
same as before.

Thanks for the hint nonetheless, I'd never have thought of that.

I've had similar problems on FedoraCore.
Setting the LANG evironment variable to:
en_US.iso885915
took care of it.
