 Not directly, but as I understand it it affects the interpretation of a 
byte stream retrieved as a character string (null-terminated in the case 
of C/C++, but possibly represented differently with other languages such 
as Pascal).  So the same byte stream may have a different character count 
depending on the encoding chosen.
