I have a problem with Serbian italics

I have this text, for example:

enter image description here

when I put the name of the book in italics without setting language (Serbian), everything is ok:

enter image description here

but when I set Serbian, I get this:

does anybody know where is the problem? I'm using polyglossia package and Linux Libertine. thank you

    Can you please add a minimal example of TeX code? – egreg Feb 11 '15 at 21:17
  • The Linux Libertine font has that variant of italic Cyrillic “d” for Serbian. Not sure if you can do anything lest than pretending the language is different. – egreg Feb 11 '15 at 21:22
  • @egreg -- i understand the "d", but not the "g", which is the fourth letter in the same word. it looks like an undotted "i" with either an overbar or a dieresis. – barbara beeton Feb 11 '15 at 21:32
  • yes, there is a problem with letter г and п. its macron, I think – Ashrak Feb 11 '15 at 21:35
  • @barbarabeeton I just saw the “d”; writing it in the shape of a Latin “g” is not so strange, perhaps. Surely the “g” and the “p’ are at least very dubious. – egreg Feb 11 '15 at 21:40
  • @egreg -- oops! didn't even spot the "p". that's just plain wrong! i think a bug report is in order. – barbara beeton Feb 11 '15 at 21:45
  • These forms are the correct ones for Serbian italics, cf https://en.wikipedia.org/wiki/Serbian_Cyrillic_alphabet#Differences_from_other_Cyrillic_alphabets If you don't like them you can change them to the variant used in other cyrillic scripts as described in the answer below, but this is definitely not a bug. – Florian Apr 19 '16 at 05:56

It's a precise choice of the font designers. When the language tag is set to SRB, the following substitutions are made in the italic font

I guess this is to imitate handwriting; the CYRILLIC SMALL LETTER PE U+403F is drawn like a “u”, with the macron to represent that the bridge should be at the top (something similar is made in Sütterlin Schrift). Similarly for CYRILLIC SMALL LETTER GHE U+0433, while CYRILLIC SMALL LETTER DE U+0434 is drawn as it is common in handwriting, as far as I know.

You can disable this with a kludge

\documentclass{article}
\usepackage{polyglossia}

\setmainlanguage{serbian}
\setmainfont[RawFeature={language=DFLT}]{Linux Libertine O}

\begin{document}

ИВИЋ,\,П.: \textit{Преглед историје српског језика.} Сремски Карловци~– Нови Сад 1998.
