Caps for Greek (and probably other) locales are not working

[GoogleCodeExporter]

What steps will reproduce the problem?
1. xdotool key Greek_GAMMA

What is the expected output? What do you see instead?
Expected Γ. Actual result γ

What version of the product are you using? On what operating system?
$ xdotool -v
xdotool version 2.20110530.1

on Ubuntu Linux 11.10 64 bit (kernel 3.0.0-17-generic) 

Please provide any additional information below.

xdotool key Greek_gamma works as expected: 
γ

This happens for all the letters of the Greek alphabet and apparently on 
Cyrillic as well. I haven' t tried any other languages.
