File rename - While displaying the name of the uploaded files in xWiki, replace the "underscore" character with "space" character

Hi All,
I have a very small but unique requirement in xWiki. We use xWiki as our document repository in one of our key products (Application)

Our application creates content in word document as part of our project requirement. Due to limitation in our application we are using “underscore” symbol in the filenames where there was a space earlier.

After the documents are uploaded into xWiki, is it possible to show the file name without the “underscore” symbol, i.e. in the list of document in the left panel, and also as a header (doc name) in the Right panel where the contents of the selected document are shown. Within xWiki, where ever the filenames appear, I want to remove the underscore symbols from the filename (while displaying only).

with regards,
G. Dorairaju
