I've come across what appears to be a tie accent over three characters in the (transliterated) name of the author of a book. Specifically, over the "liu" in this book by Bogoliubov. Is there any way to replicate that in LaTeX?
Here's an image of the typeset name as it appears in both Firefox and Safari.
The closest I can find (in 3 references: 1, 2, and 3) is the "tie" accent, \t, but I can only get that to cover two letters.
