For example, In 1990 Portuguese alphabet was extended by 3 foreign letters which are K (capa, pronounced as "kappa"), Y (pronounced as "ípsilon or "ipsilão" or "i greg"), W (pronounced as "diáblio"). Hmmm, Portugueses certainly hate W.
There are many English dialects. For example, I know about existence of British English, American English and I guess there are a couple of hundreds more dialects.
Does any of them include or plan to include foreign letters?
