示例1: normalize
func normalize(col *collate.Collator, buf *collate.Buffer, in []byte) ([]byte, error) {
// We cannot pass invalid UTF-8 to the collator.
if !utf8.Valid(in) {
return nil, fmt.Errorf("cannot normalize string containing invalid UTF-8: %q", string(in))
}
// Ref: http://dev.mysql.com/doc/refman/5.6/en/char.html.
// Trailing spaces are ignored by MySQL.
in = bytes.TrimRight(in, " ")
// We use the collation key which can be used to
// perform lexical comparisons.
return col.Key(buf, in), nil

func testCollator(c *collate.Collator) {

// iterator over all characters for all locales and check
// whether Key is equal.

// Add all common and not too uncommon runes to the test set.
