Cut & paste from TeX generated PDF files used to be a problem, because
the TeX fonts are not labeled with the correct Unicode character codes,
therefore acroread has problems converting the PDF back to Unicode plain
text correctly.

This package aims to fix this and seems worth a try:

Author Vladimir Volovich <[EMAIL PROTECTED]> (copied from [EMAIL PROTECTED]):
> The cmap package is to be used with pdf(e)latex and provides CMap
> files for various LaTeX font encodings (currently, T1, T2A, T2B, T2C,
> T5; this list will grow in the future) and a latex package which adds
> the /ToUnicode entries into the font dictionaries of fonts used in the
> document on the fly, making the resulting PDF files "searchable" and
> "cut-and-pasteable" in Acrobat Reader and other PDF previewers.
> 
> Thus, when the document uses Type 1 fonts like cm-super or other fonts
> in standard font encodings, the PDF files will contain the additional
> information in the form of CMap entries which will define the mappings
> from LaTeX font encodings to Unicode, making functions like search in
> PDF and cut-and-paste from PDF to other applications work properly.
