Lao is an adjective, Laotian can be both noun and adj.
Most English uses the word Lao more than Laotian.
Ex: Lao people, Lao songs, Lao musics ect...
I am Lao.
I am Laotian.
The Laotian population...
The Laotians need good job...
Most English uses Laos better than Lao RDP.
Either one works!
I found this tutorial on how to install Lao font and it was not easy to type Lao words, cus the keyboard layout was pretty wierd/confusing and it was very time consuming to look for Loa alphabats on my keyboard. If anyone knows where can I get Lao font that's similar to jusklao, please post its link for me here. Thank you!
