Tildes: pressing "~" then "a" results in "~a" and not "ã", as it should

[Alberto R Mitre]

The summary says it all... I have a problem with that key. I can get other combinations properly, like: á, à, ä, â... but pressing the combination "Alt gr + 4", writes the tilde "~" all of a sudden. It should wait for another input ("a", for example), and then prompt the result: "ã". Luckily my spanish keyboard has the character ñÑ on it... I guess our portuguese neighbours have the correspondant keys as well, else I don't understand how this error hasn't been reported yet!

The combination doesn't work as expected everywhere: nautilus, firefox, openoffice, unity, etc...

Hello
You have to define a compose key, using the app showed in the attached screenshot select option and choose a compose key, then press compose key AltGr ì a (with an italian layout) to have ã

Thank you for your answer. I'm afraid, however, that the "bug" is still there. Not only it didn't work, but it did mess up my keyboard. With the compose key, the tilde just disappears from where it should be (couldn't guess where it moved to, pressed every key...), and so do other keys (like the brackets {}, for instance).

I would swear I was able to type those characters without problems long ago... I believe this is a regression bug :(

This should be simple... It's just that ~ (Altgr+4 or, in the Spanish layout, also Altgr+ñ) is not considered a dead key input... it should!
