Unable to use accent chars using vino-server remote VNC desktop connection

[jfrances]

Connecting over the VNC session to gnome-remote session is not possible to use characters such as á, ä, à, â (', ", `, ^).

Tested using 'gedit', 'gnome-terminal', 'libre-office' and 'thunderbird': same results.

Same gnome-session (local-access) works as expected. For this reason language seems to be configured OK.

Thanks in advance
