Alphabetical sort puts accented names at the end

Byte order is not alphabetical order. Use a locale-aware collator, and pick the locale deliberately, because Swedish and German disagree about where "ä" belongs and both are right for their readers.

Because a user-perceived character can be several code points: an emoji with a skin tone modifier is one grapheme and up to four code points. Count grapheme clusters when the number is shown to a person, code points when it is a storage limit.

The reporting layer, until something forces it. It is the part that feels productive to build and the part nobody opens twice.
