can someone replicate this cut and paste bug?

[songbird <songbird@anthive.com>]

  when cutting and pasting from evince
to a terminal the process is translating
a "um" into a "mm"  which is a signifcant
change for a technical document.

  the source document used was downloaded from:

"http://www.nature.com/srep/2013/130425/srep01732/pdf/srep01732.pdf";

  search for the phrase

"particle size between 200–500 um"

  and copy and paste it to any text terminal, 
vi'd document, or even LibreOffice doc.  all
do the same thing and translate it from um to
mm.

  so if someone can replicate this it would
help.  if not, then i'd be stumped because
i have no familiarity with cut and paste 
underpinnings...

  thanks much,
