 Let's do windows-1252 for all locales. I enhanced my detector script to
 distinguish iso-8859-1 and windows-1252, and it turns out that the en-US
 default in 24ESR and 28 beta is windows-1252. windows-1252 is a superset
 of iso-8859-1, it's what Mozilla recommends for a fallback, and it's what
 their `FallbackEncoding::Get` falls back to if it can't understand the
 locale.
