I don't think so. These 2 representations are quite different. UTF-8 use 8
bit representation with varying character length (1-4) , while unicode use
16 bit / character by default.
msGetEncodedString is used to transform the labels during the drawing in case
if the encoding parameter is specified, but this function haven't been
utilized when retieving the shape values.
