The solution uses decodeURI which is a) not available on older browser and 
b) relies on UTF8 input data (as URLs must be UTF8 encoded).

So if we don't care about older browsers we can ensure that the data passed 
from PHP to JS in such a way is ecnoded in UTF8. Please have a look at th 
maling archive for some posts of mine on this topic.

PS: I think that decodeURIcomponent is what should be used.
