I've read from someone's post/website/blog experienced this problem too! This problem happened after he used move rootfs script to free up rootfs space, but he reflashed his device to solve this. I think this is locale problem. You can try reinstall locales from XTerm. Code: apt-get install --reinstall locales Or you can try to change the device language from Language & Region settings.
apt-get install --reinstall locales
