Delete key produces tilde

[Bilge]

When pressing the delete key it crease a tilde character (~) instead of deleting after the cursor position. However, the backspace key works correctly by deleting before the cursor position.

What is your libedit version? It seems like it was a problem back in 2003 but was fixed since then.

libedit2:
  Installed: 2.11-20080614-5

Perhaps it has something to do with using a UK keyboard layout?

[sserbin]

I doubt that. That appears to be a rather outdated libedit version - if there's a more recent version available in your system repositories it's definitely worth upgrading. Out of curiousity, what's the distributive/version you are using?
According to https://ghc.haskell.org/trac/ghc/ticket/2741 - putting bind "\e[3~" ed-delete-next-char in your ~/.editrc should fix it.

I'm using Debian GNU/Linux 7.8 (wheezy). As you say, adding that line to my ~/.editrc fixes the issue, although if you delete the last character in the line, it places the cursor before the next to last character in the line, which may be intentional but I've not seen another editor that does this before. This has the effect that, if you hold down the delete key, it will delete the entire line instead of just up to the end of the line.
