Top three things to fix

Only change the flagged IDs if an app needs basic ASCII values. Update each place that uses the ID. Keep all names and headsigns in their original language.
Some internal IDs use characters outside the basic text set. These IDs are valid UTF-8 data. This warning is only about support in older apps. It does not mean that names in other languages are wrong.
Effort: A planned ID change, not a quick text cleanup.
