keybinding involving Ctrl and Shift and letter |

This seems to be a bug.
i'm trying to set keybindings for both Ctrl+n and Ctrl+Shift+n, by:
(global-set-key (kbd "C-N") 'f1)
(global-set-key (kbd "C-n") 'f2)
however, that doesn't work.
Emacs will take both Ctrl+Shift+n and Ctrl+Shift+n to be whichever is
evaluated last. In this case, f2.
But the following works:
(global-set-key (kbd "C-S-n") 'f1)
(global-set-key (kbd "C-n") 'f2)
This seems to contradict with Meta's ways. That is (kbd "M-N") works
but not (kbd "M-S-n").

This is a legacy of ASCII. Taking a look at an ASCII chart, you'll see
that ^A (control-a) through ^Z (control-z) map to ASCII codes 1 through
26, and these control keys are not case sensitive: control-a is
equivalent to control-A.
Emacs extends ASCII, which allows us to define things like C-] which are
not present in ASCII. However, (kbd "C-N") and (kbd "C-n") still both
evaluate to ^N.
