<pre>Whilst trying to extract textual information from PDFs, it seems that the
documentation for poppler_page_get_text_layout() is not correct, or there is a
bug in poppler_page_get_text(). The documentation for
poppler_page_get_text_layout says:
"The position in the array represents an offset in the text returned by
poppler_page_get_text()".
(Note that the documentation says the same for
poppler_page_get_text_attributes).
However, this doesn't seem to be the case. The problem is described succinctly
here, complete with a short piece code which reproduces the problem:
<a href="http://www.mail-archive.com/poppler@lists.freedesktop.org/msg06238.html">http://www.mail-archive.com/poppler@lists.freedesktop.org/msg06238.html</a>
The linked PDF [1] gives 1541 glyphs from poppler_page_get_text and 1477 glyphs
from poppler_page_get_text_layout. It does not appear to be related to unicode
encoding.
In addition to the numbers of glyphs not agreeing, the order doesn't seem to
match up either, from what I can tell.
