Remind me: PDF stands for "Portable Document Format", or something else?

Yes, it is very curious, but unfortunately, pdf viewers behave very
inconsistently, especially on linux. When you use something like shading
or transparencies, you can have very nasty surprises. Though I must say
that in my experience, okular has been quite good. Adobe Reader does
some funny things with colors and makes fonts look too skinny, and
evince has some bizarre problems.

cut and paste from viewers depends on

- documentproviding tounicode
- viewer dealing with unicode
- os copy buffer dealing with unicode / locales
- receiving (editor, mailer) dealing with unicode / locales

e.g. here

- acrobat copies the proper math italic v
- sumatrapdf copies nothing
- okular copies a v
- pdftotext output nothing

so .. who knows
