Hi, 
 
I think this could be intersting for a lot of people. With the guide below, I'm now able to run wiki in a jar on a USB stick and can share all documents between Linux and Windows boxes.  
 
- download and extract the source package (wiki-in-a-jar.tar.gz) 
 
- following files needs to be changed 
file: wiki-in-a-jar/Wiki_in_a_jar/trunk/src/org/rgse/wikiinajar/helpers/TextUtils.java 
 
remove the import lines 
import java.io.FileReader; 
import java.io.FileWriter; 
 
add the import lines 
import java.io.FileInputStream; 
import java.io.FileOutputStream; 
import java.io.InputStreamReader; 
import java.io.OutputStreamWriter; 
import java.nio.charset.Charset; 
 
modify line 50: 
--- BufferedReader reader = new BufferedReader(new FileReader(file)); 
+++ BufferedReader reader = new BufferedReader(new InputStreamReader( 
new FileInputStream(file), Charset.forName("UTF-8"))); 
 
modify line 63: 
--- PrintWriter out = new PrintWriter(new FileWriter(file)); 
+++ PrintWriter out = new PrintWriter(new OutputStreamWriter( 
new FileOutputStream(file), Charset.forName("UTF-8"))); 
 
 
file: wiki-in-a-jar/Wiki_in_a_jar/trunk/bin/start.cmd 
 
modify line 2: 
--- start javaw -jar wiki.in.a.jar 3003 
+++ start javaw -Dfile.encoding=UTF-8 -jar wiki.in.a.jar 3003 
 
 
file: wiki-in-a-jar/Wiki_in_a_jar/trunk/bin/start.sh 
 
modify line 5: 
--- java -jar wiki.in.a.jar 3003 & 
+++ java -Dfile.encoding=UTF-8 -jar wiki.in.a.jar 3003 & 
 
 
- change in following files the file enoding  
from: <?xml version="1.0" encoding="ISO-8859-1"?> 
into: <?xml version="1.0" encoding="UTF-8"?> 
 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/wiki/edit.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/wiki/show.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/wiki/home.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/common/error.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/calendar/month.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/tag/tree.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/index/vcard.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/index/wiki.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/index/all.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/find/pages.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/admin/default.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/views/vcard/show.xml 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/wiki/edit-article.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/wiki/show-article.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/master.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/common/error.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/common/tag-list.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/common/sub-menu.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/common/root.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/common/main-menu.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/calendar/calendar.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/tagtree/tagtree.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/admin/admin-page.xsl 
wiki-in-a-jar/Wiki_in_a_jar/trunk/public/skins/default/vcard/vcard.xsl 
 
(if you have a GNU find and sed command on your system you can change all files in one step) 
 
cd wiki-in-a-jar/Wiki_in_a_jar/trunk/public 
find . \( -name "*.xsl" -o -name "*.xml" \) -exec sed -i '1,1 s/ISO-8859-1/UTF-8/g' {} \; 
 
- change into directory wiki-in-a-jar/Wiki_in_a_jar/trunk and compile the project
