[Harry Potter] Are there spells, incantations and potions only available to a specific region due to language barriers?

Fluer has an incredibly thick French accent; for her to produce an English spoken levitation charm pronouncing “Wingardium Leviosa” as perfectly as required, wouldn’t go over well.  So I’m assuming that there is a variation of this spell spoken in the French dialect?


And that got me into thinking that there’s probably a variation of that levitation spell in Ghana and China and Mexico.. and everywhere else.  Then this regional thinking got me into wondering if there were spells and stuff that may have been worked out in other countries, that haven’t been properly translated into a working spell to be done in the English, Spanish, Russian or other languages yet.  


Or is all based on some sort of inner magic, and the words spoken don’t really matter, they just help you focus your feelings into what you want to do magically. 


Additionally; surely there have to be potions that have been created based on the indigenous flora and fauna that aren’t (or can’t be) created elsewhere due to ingredients not being available (unless imported), right?

In canon there are regional variation to magic.  According to Pottermore, the wand is an European invention that got popular around the world in the recent century. African wizards and witches traditionally don't use a wand, and even though it is available there now, they still often just do wandless magic.  

That would suggest that the wand movements in casting a spell is not necessary for magic in general, and appears only to be needed in a European/Britain regional variation of the spell.

Animagi are also very common in Africa, whereas it's very rare in Britain.  Either their education system was different, or they just have other regional ways to make Animagi.
