sourcepub fn canonicalize(&self, locale: &mut Locale) -> TransformResult
pub fn canonicalize(&self, locale: &mut Locale) -> TransformResult
The canonicalize method potentially updates a passed in locale in place depending up the results of running the canonicalization algorithm from http://unicode.org/reports/tr35/#LocaleId_Canonicalization.
Some BCP47 canonicalization data is not part of the CLDR json package. Because
of this, some canonicalizations are not performed, e.g. the canonicalization of
und-u-ca-islamicc to und-u-ca-islamic-civil. This will be fixed in a future
release once the missing data has been added to the CLDR json data. See:
https://github.com/unicode-org/icu4x/issues/746
