Add windows encoding to Eclipse on linux

I have a legacy project which has all the source files, templates, properties written in cp1250 encoding. (Windows 1250 - central european). Recently I switched from Windows to Ubuntu and found out, that fresh installation of Eclipse 3.5 doesn't have cp1250 in neither project properties nor workspace settings. How do I install new encoding to be recognised by Eclipse?

Now that's just typical, a minute later I send the question I find out that the drop-down menu can be also edited, so it's just simply matter of writing cp1250 in there, hitting OK and voila, problem solved. Eclipse even rerenders opened editors to show applied encoding right away. Problem solved.
