Highlight of searched keywords does not work with none ASCII characters
In an internal application, where the keywords typed by the user during the search are transmit to the document-viewer portlet, using none ascii character result in empty chars in the highlight box of the docview.
For instance, if the word typed in the search portlet is "Rémi". Then the highlight box is filled with "R mi" which will hightlight every single "r" on the page, as well as all the "mi".
