A couple of minutes of research points to this post about ligature in pdf: Make ligatures in Linux Libertine copyable (and searchable). It appears that there are ways of configuring a TeX document so that ligature can be more reliably copied out of PDF as plain text (this depends on correct support of copying out by PDF readers, but some ways of creating PDFs make more readers handle this operation correctly).

Thanks Vladimir! The SingInst .tex template is going to get an update this afternoon.

I have forwarded this request to the person heading up the project to TeXify our publications.

Try the link now. Still looks pretty, and copy&paste works.

I didn't try copy/paste before. I now tried Wei's fragment, and copying out of "Th" (as well as search) doesn't work in Foxit Reader 2.3.2923 (I got "Te tiebreaker" instead of "The tiebreaker").

I tried opening the PDF in Google Chrome (17.0.963.66 m/win32 XP) using its in-built viewer, and it doesn't open at all.

2.3? Wow. I'm on Foxit Reader 5.4.1. Perhaps that's what is making the difficulties?

Did you try copying the 'Th' by itself? My reader (Mac OS X's Preview) gives me only the first letter when I try to copy a single ligature but works if I include the next character in the selection.

Also, initially Chrome failed to open it for me too but succeeded on another try. Weird.

Edit: added name of the reader.

Reloading in Chrome worked (I checked with md5sum that it's the same file as before, when it didn't work), and copying out of "The" works from Chrome. Foxit Reader doesn't work, no matter how "The" is copied.

(Both you and Luke didn't name their readers where copying works, which is unhelpful if you're mentioning the fact that it works somewhere at all.)

Copy-paste works for me in Adobe Acrobat Pro 9 and in Chrome.

I just clicked on the link in the opening post and it opened in my foxit reader. I then copy and pasted this:

came first. The original

Can you confirm this for me please Vladimir? Perhaps do a "Save file as" then open externally? Or perhaps some sort of force reload? We need to be sure it isn't a cached version. Actually, I'll email you one.

If you are having problems with Foxit Reader (my primary test case) then we have something of a problem! (In that case I will try, for example, installing foxit on a virtual machine that doesn't have the fonts installed to check if it is an embedding issue.)

While you are at it, could you see if it works in Adobe Acrobat Reader? It certainly should but if you have the same problem with adobe as you do with foxit it would tell us something.
