ASCII in Business Central Cloud

ASCII: A thing from the past? Not in Dynamics NAV! - Views on Dynamics 365 Business Central - Dynamics 365 Business Central/NAV User Group - Dynamics User Group

How it is being handled in case of export of files in BC Cloud as there is no server to configure ASCII encoding or which encoding is used in these cases for different countries other than ENGLISH.

As some banks do only prefer a specific format as per their specified format and encoded it that specifically.

I read about UTF-8 where it says it understands ASCII , but how actual exported data encoding will be, I want to understand this?
