multiples search and replace in the same command?

[Tanoor Dieng]

Hi, i'm trying to replace all occurrences of characaters like é, è, ê
etc ... by their corresponding htmlentities. To do that, i use the
following command:
%s/é/\é/g

The problem with that command is that i have to do that for all
characters. I was wandering if there's a way to do it with only one
command.


Best regards.
