;  The string now contains: "é é é"
ConsoleWrite($oSb.GetAsString() & @CRLF)

;  If encoded to hex using the iso-8859-1 charset, 
;  each é char is represented in 1 byte.

ConsoleWrite($oSb.GetEncoded("hex","iso-8859-1") & @CRLF)

;  If encoded to hex using the utf-8 charset, 
;  each é char is represented in 2 bytes.
