// Package unicode provides an alternative to the SQLite ICU extension.
//
// Like the [ICU extension], it provides Unicode aware:
// - upper() and lower() functions,
// - LIKE and REGEXP operators,
// - collation sequences.
// - upper() and lower() functions
// - LIKE and REGEXP operators
// - collation sequences
//
// Like PostgreSQL, it also provides:
// - initcap(),
// - casefold(),
// - normalize(),
// - unaccent().
// - initcap()
// - casefold()
// - normalize()
// - unaccent()
//
// The implementations are not 100% compatible:
// - upper(), lower(), initcap() casefold() use [strings.ToUpper], [strings.ToLower], [strings.Title] and [cases];
// - normalize(), unaccent() use [transform] and [unicode.Mn];
// - the LIKE operator follows [strings.EqualFold] rules;
// - the REGEXP operator uses Go [regexp/syntax];
// - collation sequences use [collate].
// - upper(), lower(), initcap() casefold() use [strings.ToUpper], [strings.ToLower], [strings.Title] and [cases]
// - normalize(), unaccent() use [transform] and [unicode.Mn]
// - the LIKE operator follows [strings.EqualFold] rules
// - the REGEXP operator uses Go [regexp/syntax]
// - collation sequences use [collate]
//
// Expect subtle differences (e.g.) in the handling of Turkish case folding.
