There isn’t really a way to check unfortunately. I know the German ones use dashes instead of pixel-dots, so those can be distinguished. But for English vs French, I don’t think there is a way to tell, except by overlaying it with its paired cards.
I only have the Jessie in English, but here for example the English, French, and German Seviper as example, and to also show that the English and French ones are apart from the positions of the pixel-dots identical:
Greetz,
Quuador
Well there kinda is if the German cards use slashes instead of dots, there aren’t any other languages besides these three so you can just compare for example Jessie and James to the ones here and if it’s a different one it’s a Spanish copy
I think the statement about German cards using slashes instead of dots is true for the Human/Pokemon match up cards. But from what I can find, all languages use slashes instead of dots for the Attack/Pokemon match up cards. It’s very hard to tell the language on those Attack/Pokemon match ups, although some do have clear accent marks that help determine language. You really have to find images online of a matched duo of cards and compare the slashes/dots to the words being formed.
For attack/pokemon match ups you can use the attack list photo from my original post, it’s usually quite easy to tell from the options which word the slashes will form, for example with grimer the difference with slashes is clear if the word is matchbombe or bomba lodo 
Also, i had the languages mixed up in my previous post so edited that
