I inspected the pdf file, and its font encoding is termed "Identity-H". I couldn't reveal much about this encoding, but it seems to be a private encoding of Adobe used especially for Asian fonts.

Betreff: Joined "ti" coded as "Ɵ" in PDF
Odd result when copy/pasting text from a PDF: For some reason "ti" in
the (English) text of the document at
http://web.isanet.org/Web/Conferences/Atlanta%202016/Atlanta%202016%20-%20Full%20Program.pdf
is coded as "Ɵ". Looking more closely at the original text, it does
appear that the glyph is a "ti" ligature (which afaik is not coded as
such in Unicode).

Out of curiosity, did a web search on "internaƟonal" and got over 11k
hits, apparently all PDFs.

Anyone have any idea what's going on? Am assuming this is not a
deliberate choice by diverse people creating PDFs and wanting "ti"
ligatures for stylistic reasons. Note the document linked above is
current, so this is not (just) an issue with older documents.
