I don't think so. However, if you declare that to be a Unicode string,
the parser will decode it using the declared encoding, and it'll be a
five-character string. At that point, it doesn't matter what your
source encoding was, because the characters entered will match the
characters seen.

Entry(u"=D1=82=D0=B5=D0=BA=D1=81=D1=82")
