I guess that I formulated that poorly : Having to default to one of the UTF-16 instead of UTF-8 is another complication that makes it harder to do Unicode properly. (What happens when you paste UTF-8 into a UTF-16 file ?)

And I guess that they have to follow the lead of Matlab anyway, at the risk of going into another direction... EDIT : Yeah : https://savannah.gnu.org/bugs/?57103#comment7

Speaking of which, I should check how Scilab deals with it!
