 Note that canonicalization does not change invalid locales to valid locales. For example, und-u-ka canonicalizes to und-u-ka-true, but:
 
-1. "und-u-ka-true" — is invalid, since ‘yes’ is not a valid value for ka
-2. "und-u-ka" — is invalid, since the value “true” is assumed whenever there is no value, and ‘true’ is not a valid value for ka
+1. "und-u-ka-true" — is invalid, since "true" is not a valid value for ka
+2. "und-u-ka" — is invalid, since the value "true" is assumed whenever there is no value, and "true" is not a valid value for ka
 
 The BCP 47 form for keys and types is the canonical form, and recommended. Other aliases are included for backwards compatibility.
