Alkuperäinen teksti - Romania - A fost odată ca niciodată

This means Once upon a time. Should they be considered as isolated words?

Doesn't it mean : "once upon a time there was..."
As this is kind of idiomatic and universal(in French we're using a verb in this sentence "il était une fois"

This may be interesting to know about how it is translated
into other languages.

I would personaly agree about translating this expression

Me too; there is an article with the translation of this expression in many languages.
