Function EncodeLocaleName

pkg/sql/lex/encode.go:45–62

EncodeLocaleName writes the locale identifier in s to buf. Any dash characters are mapped to underscore characters. Underscore characters do not need to be quoted, and they are considered equivalent to dash characters by the CLDR standard: http://cldr.unicode.org/.

(buf *bytes.Buffer, s string)

// need to be quoted, and they are considered equivalent to dash characters by
// the CLDR standard: http://cldr.unicode.org/.
func EncodeLocaleName(buf *bytes.Buffer, s string) {
	// If possible, try to normalize the case of the locale name (only for non-default
	// locales). Default locales will always be quoted so they can be parsed correctly.
	isDefaultLocale := collatedstring.IsDefaultEquivalentCollation(s)
	if isDefaultLocale {
		s = fmt.Sprintf("%q", s)
	} else if normalized, err := language.Parse(s); err == nil {
		s = normalized.String()
	}
	for i, n := 0, len(s); i < n; i++ {
		ch := s[i]
		if ch == '-' {
			buf.WriteByte('_')
		} else {
			buf.WriteByte(ch)
		}
	}

// LocaleNamesAreEqual checks for equality of two locale names. The comparison
// is case-insensitive and treats '-' and '_' as the same.
