Biblatex Localized Items

Question

I am preparing a document where I am using Biblatex + Polyglyossia + XELATEX. I have citations in both languages English and Arabic. The localized items appear in English in Arabic citations, also upon using the cs quotes package which is a must in biblatex package, CS QUOTES have no quotation for Arabic language. I have 3 issues:

• How to make footnote citations and bibliography change from right to left or left to right according to language

• Localized items (the words edition, page,seenote,and), how to remove them or make them appear according to the citation language

• CS quotes have no definition for Arabic language.

\documentclass[a4paper,12pt,twoside]{book}

Here is the reference format

@book{Sharoni1969,
 author = {ميخائيل، ملاك  and  الشاروني، حبيب},
 year = {1969},
 title = {المرجع فى قواعد اللغة القبطية},
 address = {الاسكندرية},
 publisher = {{جمعية مارمينا العجايبي}}
}

@book{Browning1983,
 author = {Browning, Robert},
 year = {1983},
 title = {Medieval and Modern Greek},
 publisher = {{Cambridge University Press}},
 isbn = {0521299780 9780521299787}
}

Answer 1

I couldn't do this with polyglossia and xelatex.

But here's a go with babel and lualatex that might offer a way forward.

You have to create arabic.lbx for strings for biblatex and define Arabic quotes for csquotes. (I'm not sure about either the quotes or the translations…)

MWE

There's some comments in the code below explaining things a bit.

\documentclass[12pt]{article}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@book{Sharoni1969,
 author = {ميخائيل، ملاك  and  الشاروني، حبيب},
 year = {1969},
 title = {المرجع فى قواعد اللغة القبطية},
 address = {الاسكندرية},
 publisher = {جمعية مارمينا العجايبي},
 langid = {arabic}
}
@book{Browning1983,
 author = {Browning, Robert},
 year = {1983},
 title = {Medieval and Modern Greek},
 publisher = {Cambridge University Press},
 langid = {english}
}
\end{filecontents}

\begin{filecontents}{arabic.lbx}
\ProvidesFile{arabic.lbx}
\InheritBibliographyExtras{english}
% Translations thanks to Google Translate.
% I haven't provided abbreviations, because I don't know Arabic.
% You'll need to add more for other strings you use.
% Look in `english.lbx` for the string name.

  seenote          = {{انظر الملاحظة}{انظر الملاحظة}},
}
\end{filecontents}

\usepackage[nil,bidi=basic-r]{babel}

\usepackage{csquotes}
\DeclareQuoteStyle{arabic}

% Always use Arabic digits for see note.

  {\ref{cbx@\csuse{cbx@f@\thefield{entrykey}}}}

% Just to test if quotes work
\DeclareFieldFormat{title}{\mkbibquote{\mkbibemph{#1}}}

% With the above, the language changes back to Arabic before the final period
