"Duplicate case " on switch statement by GWT compiler

[Didier DURAND]

Hi everybody,

I need to escape utf-8 to their html format.

I use the function below and the gwt compiler to JS doesn't like it:
it says "duplicate case" for all cases starting with and after the
à

a) Can somebody tell me what I am doing wrong ?

b) Is there any better way (using official GWT code) to do it ?

thanks
didier
