love-console's Issues

utf8 not sopport

crash the game when write utf character

~ key

At console.lua, at line 275 change this (~):

function console.textinput(input)
  -- Use the "~" key to enable / disable the console.
  if input == "~" then
    enabled = not enabled
    return
  end

to this (`):

function console.textinput(input)
  -- Use the "~" key to enable / disable the console.
  if input == "`" then
    enabled = not enabled
    return
  end

built in print() command returns nil

Whenever you can print() in the command line; it adds an additional 'nil' line at the end.
I assume this is a bug because it doesn't happen to any user implemented commands.
