fix(library): sort names with accents set aside - #805
Conversation
COLLATE NOCASE folds ASCII only and the scanner's canonical forms keep their accents, so an artist starting with an accented letter sorted after Z while the A-Z rail filed it under its base letter. A FOLD collation, registered on the profile pool, compares case- and accent-folded first (the fold the remote sort keys use), then breaks ties on case and bytes so the order stays total. Name listings use it; paths, codecs and grouping keep NOCASE.

FOLD now decomposes (NFD) and drops the marks, so letters outside the normalize_name table (R with caron, S with cedilla, Vietnamese) sort with their base letter; stroked letters NFD leaves whole get a small table. ASCII pairs skip the decomposition. Docs say the keys sort together rather than compare equal.

@coderabbitai On the RFC-005 outside-diff comment: fixed in ddaf79e. The section now distinguishes the local canonical_* keys (accents kept) from the remote sort_title / sort_artist (normalize_name, accents folded), says the unified query orders the projected keys with COLLATE FOLD, and that COALESCE supplies the display title and artist for rows mirrored before the sort columns existed. It also says the keys sort together rather than compare equal, since FOLD breaks ties on case and bytes. |

Problem
Library listings sorted names with
COLLATE NOCASE, which folds ASCII only. The scanner'scanonical_name/canonical_titlekeep their accents, so an artist or album starting with an accented letter ("Émilie Simon", "Ödland") sorted after Z, while the A-Z rail files it under its base letter. With the unified library, a local accented name and its mirrored counterpart (whose sort key is already folded bynormalize_name) also landed in two different places.Fix
waveflow_core::repository::sqlite::collation: aFOLDcollation that compares case- and accent-folded first, using the same fold asnormalize_name(nowpub(crate)helpers), then breaks ties on lowercase and bytes so the order stays total and stable between queries. No allocation per comparison.profile_db::open).COLLATE FOLD: albums, artists, tracks (title / artist / album and the default order), genres, the artist and genre detail pages, search suggestions, the folder browser's order, and the coreSqliteTrackRepository.
