Popup virtual keyboard that allows international characters

Question

I'm looking for a specific Javascript solution for an application we're working on. We actually used to have it, but we've lost it (facepalm). What happened was the following:

1. Click keyboard image
2. Virtual keyboard popped up allowing user to choose a bunch of international keys (such as umlauts for Germany, Cyrillic for Serbian, etc.)

I've done various searches on Google for "Javascript popup keyboard", "Javascript international keys keyboard", "Virtual javascript keyboard", etc. but have found no results. Then, I remembered MooTools and the amazing job they do and found a virtual keyboard that does something similar, but not exactly what we want.

Unfortunately, it only displays once the character 'a' is typed (and displays all variations with umlauts, strikes above, etc.) What we need is that virtual keyboard that displays once an image is clicked and shows ALL international characters.
