ve, va, vi, fa etc in katakana

[visser300]

These words are definitely not portrayed in katakana characters. But I've seen many websites & games of Japanese using these characters.

May I have explanation from JREF members?

There IS katakana for them, ヴェ, ヴァ, ヴィ, ファ, respectively. Those are basically used only for loan words or foreign words.(ヴェトナム, for instance)

There is a big list of these "extended katalana" forms at Transcription into Japanese - Wikipedia, the free encyclopedia
