The command completed with an error (see attached). After a reboot, the 'language support' seems normal and I rearranged so that zh_TW come next to zh_HK. Some commands output (apt-get) does fallback to zh_TW, but the GUI such as the 'Personal', 'System' and 'Hardware' titles under system settings do not look perfectly as expected (see attached).
