To activate the ebook package, one has to put \usepackage{ebook}
in the preamble, and \ebook
in the document. If both are activated, \mkbibbold
stops working while \textbf
works fine. Why is that?
I use XeLaTeX -> Biber-> XeLaTeX.
WME
\documentclass{report}
%\usepackage{ebook}
\usepackage[style=authortitle,url=false]{biblatex}
\addbibresource{Qu.bib}
\renewcommand*{\newunitpunct}{\addspace\bibrangedash\space}
\DeclareFieldFormat*{title}{\mkbibbold{#1}}
\begin{document}
%\ebook
\textbf{Bold text} \textit{Italic text}
\nocite{*}
\printbibliography[heading=subbibliography,keyword=Projective geometry,title=Hình học xạ ảnh]
\end{document}
Results
If \renewcommand{\bibfont}{\textnormal}
is used, then the heading is not large anymore
ebook
-- it is not good.
