It also test normalize(locale_alias[localname]) == locale_alias[localname]
== normalize(localname). I.e. that applying normalize() twice doesn't
change a result.

chinese-s is mapped to zh_CN.eucCN, but eucCN is mapped to gb2312. sp is
mapped to sr_CS.ISO8859-5, but sr_CS is mapped to sr_RS.UTF-8 and then
.ISO8859-5 replaces UTF-8. Of course we can recursive call normalize(), but
it will be more practical just update the mapping.
