GDB print string in an wrong format, a little like octal string

问题

I show charset in my gdb:

The host character set is "UTF-8".
The target character set is "UTF-8".
The target wide character set is "auto; currently UTF-32".

But when I try to output a string in a register

p (char*) $register

I got a very strange string which hard to recognise:

$16 = 0x100001040 "A\020\021\021\033\ndgjhbhnghkb=ejj=h\004\005\b\003 ...

I am sure that if the string is purely ascii, all works fine.

So what should I do to get the string I want to see?
