Well, the problem stems from the MetricInfo of CID-keyed fonts, which 
are intended only for use for the glyphs of East Asian languages, which 
are all monospaced and are all treated as filling the same bounding box. 
(from the help page of CIDFont)

However, is it possible to use the same MetricInfo of CID-keyed fonts as 
that for png() or windows()?
