Description of problem:
Wrongly recognize input '|' to '>' in qemu guest via vnc

Version-Release number of selected component (if applicable):
tigervnc-icons-1.8.0-4.el7.noarch
gvnc-0.7.0-2.el7.x86_64
tigervnc-license-1.8.0-4.el7.noarch
gtk-vnc2-0.7.0-2.el7.x86_64
gtk-vnc-debuginfo-0.7.0-2.el7.x86_64
tigervnc-1.8.0-4.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. In one terminal on the host, boot a guest via qemu with '-vnc :0'
(qemu) info vnc
default:
  Server: :::5900 (ipv6)
    Auth: none (Sub: none)
  Server: 0.0.0.0:5900 (ipv4)
    Auth: none (Sub: none)
  Client: ::1:38890 (ipv6)
    x509_dname: none
    sasl_username: none

2. In another terminal on the same host, start vncviewer
# vncviewer :0

3. in the guest, in the vnc window -> open a terminal -> input '|'(shift+\) or '<'(shift+,), they will be recognized as '>'.

Actual results:
in the guest, in the vnc window -> open a terminal -> input '|'(shift+\) or '<'(shift+,), they will be recognized as '>'.


Expected results:
input '|'(shift+\) --> show '|'
input '<'(shift+,) --> show '<'

Additional info:
1. works well via ssh to login guest
2. same problem via remote-viewer
