I have a standard desktop UI install of the latest Ubuntu distro and I'm trying to view this page: http://www.i18nguy.com/unicode/supplementary-test.html.
However none of the text display properly. I have tested this on Windows 8 and I can see them just fine.
My locale output is as follows:
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
I have also found the terminal also doesn't display many unicode characters.
