Why would anyone pick UTF-16LE? All the disadvantages of UTF-8, none of the advantages. The only reason to use it is when dealing with legacy systems that used it.

Code point order would be somewhat decent, but even better is to use the user’s chosen coallation order from their locale settings if possible.

The languages in a language menu should each be written in their own language. So German should be “Deutsch”, English should be “English”, Japanese should be “日本語”, etc.
