I'm trying to enter a tab character in Firefox/Chrome text boxes without having to copy-paste from Emacs. The combination Ctrl+Shift+U then
0009 does not work. In fact, it does not seem to work for most "control" characters. However, it works for pretty much any printable character including non-ASCII. This is really bizarre. Google doesn't seem to reveal any such inconsistent behavior. Anyone know why this combination bans whitespace? I can repeat this behavior in any program including Leafpad and LibreOffice.
