How much space pre character is taken when UTF-8 is used in SAS

[Aspoyam]

In standard definition for UTF-8 is used 1-4 bytes per character, if UTF-8 is used. It works like this calculator:

But how it's in SAS? Does SAS used 3bytes per character by default and it doesn't matter what character is stored?

Thank you,

UTF-8 in bytes is a function of language not of SAS.

Special characters will use one byte each.

Letters will use - latin (A a B b etc.) 1 byte each.

language specific characters (french, german, nordic, chinese, hebrew, arabic etc.) will use at least 2 bytes each.
