Jonathan,
You are obviously much more advanced than I am. Just a couple thoughts.
My computer is 64 bit and both my Windows and Ubuntu versions of LibO are 64
bit, and I have the same problem as you.
Again, my AOO (on either Windows or Ubuntu) doesn't have the problem but I
don't know if it is specifically a 64 bit version. I just downloaded
whatever popped up from the download page.
I'm beginning to think that the problem may be in the PDF converter
settings. I tried checking and unchecking the "imbed standard fonts" option,
but it made no difference. I'm still thinking that there's a problem in the
way LibO creates PDF files as opposed to AOO.
Good luck.
Virgil

Hi all,
Thank you for all your enthusiastic help with this.
I also made some progress. Using Infix PDF Editor 5 (Windows trial
version under Wine) and/or fontforge (Linux) I could see that the Font
mapping was messed up. The mistaken mappings begin:
Th -> T
i -> hi
That is, the PDF converter has broken 'This' at the wrong place into
'T/hi/s' instead of 'Th/i/s'. All successive instances of the 'i' glyph
are mapped to 'hi', thus explaining the drunken slurring effect.
I was able to manually repair the mappings using podofobrowser
(Opensource, pre-built Windows executable under Wine). Now my real PDF
is good. But if I re-create it I need to re-repair it.
I've reproduced the problem with both Debian and the LO versions of LO.
Maybe I should also try installing AOO.
webmaster-Kracked_P_P: would you be able to attach the PDF that you
produced from my file so I can look for signs?
My version of the fonts is from January 2012, so that may be a source of
the problem. Another possibility, since it's fairly clearly a bug
somewhere, is that maybe building for 64 bit architecture makes it
disappear.
Unless anyone has a better idea, I'll file this as a LO bug.
Cheers,
Jonathan

Interesting problem. Based on my tests, which I detail below, it appears
to be LibO bug rather than a font problem.
I'm using LibO 3.5.6.2 with Win7 and Adobe Reader.
In the sentence "This is the official version" with Linux Libertine G,
there are two instances of automatic ligatures--the "Th" combination in
"This," and the "ffi" combination in "official." In Adobe Reader, I aas
able to find "This" when I did a search, which means that the Reader
recognized the "Th" ligature as a "T" followed by an "h" which is what I
typed into the search box. But, when I tried to search for "official"
the Adobe Reader couldn't find it, which means it did NOT associate my
typing of an "f", "f", "I" with the "ffi" ligature.
Then when I copied and pasted the sentence from the PDF file into a
plain text editor, it placed an "h" before every instance of an "i" just
as was reported. However, this obviously has nothing to do with
ligatures as most of the instances of "i" were NOT included in the
ligatures. In fact, it did not place an "h" before the "i" in the "ffi"
ligature.
For comparison, I ran the same test using Apache OpenOffice 3.4.1. to
see if it is a font issue or a program issue. I'm sorry to report that
it appears to be a program issue. In AOO, I typed the same sentence
using Linux Libertine G, "This is the official version." I then saved it
as a PDF and opened it in Adobe Reader. This time, a search found both
"This" and "official" despite both words containing ligatures. And, when
I copied the sentence into a plain text editor, it copied correctly
without any additions of "h" before "i".
I love the Linux Libertine set of fonts. I use it, not only with LibO
and AOO, but also when I set a document in LaTeX.
I have found that Apache OpenOffice's support for Linux Libertine G
appears to be more complete and polished than LibO's. This may be an
example of that more complete support.
Of course, LibO has its advantages over AOO; for example, it properly
hyphenates American English words, with AOO does not appear to do. It
would be nice if someone could combine the best of both programs into
one complete program (along with the tabbed interface of Lotus Symphony,
yet a third fork of the original OO). But, I won't hold my breath.

That's exactly what I mean. It effectively means no searching.
I tried both Linux Libertine and Linux Biolinum [14 point] on my
3.5.7 version for Ubuntu 64-bit. I cannot replicate the issue with
"added" characters.
Were you using Graphite fonts ('Libertine G'/'Biolinum G')? Those are
the ones where the problem arises. Those are also the fonts that do
ligatures and other lovely typesetting things that make them look so
nice, which I why I want to use them.
Cheers,
Jonathan
Seems to me that you have solved your own problem: it is the
fonts. The search function can not handle the the lovely typesetting
things. As you mentioned, an "i" looks like a "hi" to it. The only real
solution is to not use any of the Graphite fonts in a PDF.
But if you want to search the PDF, have you opened it in Draw and
search for the text in it?
