Some more investigation of the behavior of Adobe Reader 7.0.9 (Windows):

I'm not sure I should use Adobe Reader as a guide for proper behavior.  My test
file is http://www.irs.gov/pub/irs-pdf/f1040.pdf.  Adobe Reader is exhibiting
some rather strange behavior here: the default appearance string for most form
fields specifies /HeBo (Helvetica-Bold) as a font, but when editing a field and
saving the resulting file, it looks like Adobe Reader is using
/Helvetica-Condensed-Bold as a font.  Additionally, the two fonts have a
different encodings specified (WinAnsiEncoding vs. StandardEncoding) so it's
not so surprising that some character encoding issues are coming up.

At the very least, it does seem that Adobe Reader will decode form field values
that are encoded in UTF-16 (though it still displays them incorrectly).  So,
using UTF-16 for form field values in poppler seems reasonable.

I'll see if I can't clean up my earlier patch a bit and post something.
