Receive only a wchar_t in tchar()

It makes simpler the conversion from utf8 input string and
makes simpler the checks done in tputc, but it still requires
a lot of additional conversions that will be removed later.

 It means that st doesn’t have any terminfo entry on your system. Chances are
-you did not make install. If you just want to test it without installing it,
-you can manualy run tic -s st.info in st dir. It will compile st.info into a

 * Some programs just assume they’re running in xterm i.e. they don’t rely on
   terminfo. What you see is the current state of the “xterm compliance”.
 * Some programs don’t complain about the lacking st description and default to
   another terminal. In that case see the question about terminfo.

+
+## Backspace key does not work
+
+This is an issue that was discussed in suckless mailing list
+<http://lists.suckless.org/dev/1404/20697.html>:
+
+	Well, I am going to comment why I want to change the behaviour
+	of this key. When ASCII was defined in 1968, communication
+	with computers was done using punched cards, or hardcopy
+	terminals (basically a typewriter machine connected with the
+	computer using a serial port).  ASCII defines DELETE as 7F,
+	because, in punched-card terms, it means all the holes of the
+	card punched; it is thus a kind of 'physical delete'. In the
+	same way, the BACKSPACE key was a non-destructive backspace,
+	as on a typewriter.  So, if you wanted to delete a character,
+	you had to BACKSPACE and then DELETE.  Another use of BACKSPACE
+	was to type accented characters, for example 'a BACKSPACE `'.
+	The VT100 had no BACKSPACE key; it was generated using the
+	CONTROL key as another control character (CONTROL key sets to
+	0 b7 b6 b5, so it converts H (code 0x48) into BACKSPACE (code
+	0x08)), but it had a DELETE key in a similar position where
+	the BACKSPACE key is located today on common PC keyboards.
+	All the terminal emulators emulated the difference between
+	these keys correctly: the backspace key generated a BACKSPACE
+	(^H) and delete key generated a DELETE (^?).
+
+	But a problem arose when Linus Torvalds wrote Linux. Unlike
+	earlier terminals, the Linux virtual terminal (the terminal
+	emulator integrated in the kernel) returned a DELETE when
+	backspace was pressed, due to the VT100 having a DELETE key in
+	the same position.  This created a lot of problems (see [1]
+	and [2]). Since Linux has become the king, a lot of terminal
+	emulators today generate a DELETE when the backspace key is
+	pressed in order to avoid problems with Linux. The result is
+	that the only way of generating a BACKSPACE on these systems
+	is by using CONTROL + H. (I also think that emacs had an
+	important point here because the CONTROL + H prefix is used
+	in emacs in some commands (help commands).)
+
+	From point of view of the kernel, you can change the key
+	for deleting a previous character with stty erase. When you
+	connect a real terminal into a machine you describe the type
+	of terminal, so getty configures the correct value of stty
+	erase for this terminal. In the case of terminal emulators,
+	however, you don't have any getty that can set the correct
+	value of stty erase, so you always get the default value.
+	For this reason, it is necessary to add 'stty erase ^H' to your
+	profile if you have changed the value of the backspace key.
+	Of course, another solution is for st itself to modify the
+	value of stty erase.  I usually have the inverse problem:
+	when I connect to non-Unix machines, I have to press CONTROL +
+	h to get a BACKSPACE. The inverse problem occurs when a user
+	connects to my Unix machines from a different system with a
+	correct backspace key.
