Lite UI has internationalization issues

Hello,
Using the lite UI I found some problems which would be nice if they were addressed in next UI

First, accent support is very iffy, we translated part of nav.properties, but sometimes (like on buttons) the html entities were shown (e.g. é) instead of the value (é). There's some problems with encoding between Lite UI and Admin UI (one will show the character é while the other will show a question mark)

Also, if I enter some text for a grouper entity (an attribute in this case), accents are bugged :
