Street Fighter Alpha 2 was released in February 1996 in Europe and in March 1996 in the USA.
In these export releases:
Nash is named Charlie.
Vega is named M. Bison.
Gouki is named Akuma.
Shin Gouki is named Shin Akuma.
Satsui no Hadou ni Mezameta Ryu is named Evil Ryu.
In the original Japanese version, specific locations are displayed on the 'next stage' screen. All export versions just tell you which country the stage is in. Perhaps someone at Capcom USA was too lazy to translate the location-specific text (which is in Japanese) and just used the country name (which is in English). Below are the place names that were left out of the non-Japanese versions, translated into English...
