You need to pass a UTF-8 encoded simple string, and not a Unicode
string.  If you really do have a Unicode string, say, in a variable
called `s', you could write

  canvas.Canvas.drawString(5.0805*mm, 22.5*mm, s.encode('UTF-8'))

But the string you used does not look Chinese to me.  It is a sequence
of the following Unicode characters:

  U+00E5  =E5  LATIN SMALL LETTER A WITH RING ABOVE
  U+00BC  =BC  VULGAR FRACTION ONE QUARTER
  U+00B5  =B5  MICRO SIGN
  U+00E7  =E7  LATIN SMALL LETTER C WITH CEDILLA
  ...

If the text is already encoded in UTF-8, just drop the u prefix.  If it
is encoded in some other encoding, you need to recode it to UTF-8.


AFAIU there are plans to support Unicode strings directly in future
versions of Reportlab (once Python 1.5.2 compatibility is dropped).

It would be a good idea to say what results you saw and what your
expectations were.
