Load Resource Bundle

I've tried to use this plug-in and working fine for the most part but I've found an issue that I can't seem to resolve within this plug-in:

inside the properties file I have a row: "caseDetails=DÉTAILS DU CAS"

when using the loadbundle() function the row is being returned from that properties file as "caseDetails:D�TAILS DU CAS"

I can replace char(65533) with char(233) when displaying this value. This solution is clearly not perfect since I am needing to assume that the � char should in fact be a É, but the same seems to be true with other accented chars. 

A more graceful way of handling this is to simply replace this label function/plug-in with:

if(
userlocale(
loggedInUser()
) = "fr_FR",
"DÉTAILS DU CAS",
"CASE DETAILS"
)

Of course there are a number of other ways I could do this (reference data held within a DB, using constants etc) but given that the plug-in suggests it works with complex characters I feel that I am missing something (also this loadbundle function seems to be substantially quicker than retrieving the same number of "translations" through a DB query, so my current preference is to stick with this plug-in)

Any thoughts?
