In case it helps Steves fix works if you add the following to Info.plist 
once it has been created by AppBundler

<key>LSEnvironment</key>
<dict>
    <key>LC_CTYPE</key>
    <string>UTF-8</string>
</dict>

BTW I tried using infinitekind fork, but there doesn't seem to be a 
prebuilt binary. I downloaded the source and ran ant
but it complained unable to find gcc. Fixing this is probably obvious to 
a Mac developer but for a Java developer like myself whose main dev 
platform is windows and just knows the minimum about macs
  to get by its a headache.
