Fedora release 28 (Twenty Eight)
[boomer@bzha ~]$ sh 1.sh

you see, it show chinese characters which is expected in fedora28, then show octal characters in centos7, my question is how to make it show normal characters in centos7 ?

  • Can you check if `echo $'\344\275\240\345\245\275.txt'` is the same as `echo "你好.txt"`? Can you post the output of `locale` on both os-es? – KamilCuk Nov 14 '18 at 08:47

They are not garbled, they are unambiguous. You will notice that the shell reformats many other strings with set -x, too.
