Thanks, nice solution, it works as expected. The problem is that this grepping is part of a large script file, so, is there anything I can do so as to detect if the term I want to search contains not very usual letters like the above?

And if yes, then is there any way with which I can replace the %C3s etc with \xC3s so as to search the term, without possibly altering the rest of the string?

That seems a bit difficult :O
