Hi Adrian.

I attached the pdf but mind it's Serbian so, it's written in Cyrillic
script. However even if you're an ignoramus of Slavic / Cyrillic stuff,
you can casually select portions of text and notice random blank spaces,
and when you paste this selection to an external text editor, you'll see
either random black spaces or weird characters.

About the glyph mapping, I concur with your explanation as far as the
main text is concerned, but why do glyphs don't change at all (according
to the substitution table) in the right panel? This has nothing to do
with mapping, it's just that those glyphs are ignored by the program.

Greetings

Title:
  Document viewer does not support OpenType features

Status in “evince” package in Ubuntu:
  New

Bug description:
  Document viewer does display alternative glyphs activated through the
  OpenType tables but when I try to copy/paste outside of it, instead of
  the glyphs I only see a blank space. Most probably, that means that
  Document Viewer isn't able to "connect" the glyph with the underlying
  character code. Example: in a Serbian text U+0431 CYRILLIC SMALL
  LETTER BE has a Serbian localized glyph, which is different from the
  standard glyph, but when I copy that text, in the worst case scenario
  I should still be able to see a standard BE, leaving to the receiving
  program (Text Editor, Writer etc...) the capability (or incapability)
  to process OpenType features. But I only get a blank space instead.

  The right panel (with indexes etc...) doesn't even display the "weird"
  glyphs, only standard ones, and this is an additional nuisance, as the
  appearance turns out to be different from the main text.

  Another example: ligatures ct, ff, fi, etc... I get the same problem,
  they disappear, not just the ligatures, but the characters themselves,
  when I copy/paste.

  This is a very complicated issue, but I hope I've been able to make my
  point reasonably clear.
