I’d guess it’d be a particular collation, rather than Unicode order…otherwise ö would always come after z (which is incorrect for English, but correct for, e.g., Swedish).

Really? Wouldn't that depend on how you spelled it and what kind of Unicode ordering you specified?

Which comes first?

    '\u0047\u00f6\u0064\u0065\u006c'
    '\u0047\u006f\u0308\u0064\u0065\u006c'
