# Using Biblatex with utf8x

I'm trying to write a thesis proposal which includes a sentence in Hebrew.

I use the following:

\documentclass[a4paper, 12pt]{article}
\usepackage[top=1in, bottom=1in, left=1in, right=1in]{geometry}
\usepackage{ucs}
\usepackage{graphicx}
\usepackage{float}
\usepackage{mathptmx}
\usepackage{setspace}
\usepackage{anyfontsize}
\usepackage[sorting=none]{biblatex}
\usepackage{t1enc}
\usepackage[utf8x]{inputenc}
\usepackage{culmus}
\usepackage[english,hebrew]{babel}

\begin{document}

\L{\huge{hello hello}}
\end{spacing}

\medskip
\Large{שלום}

\section{References:}}

\end{document}


Im getting the following error:

Incompatible package 'ucs'. See the biblatex package.


I read that there is a problem using utf8x with biblatex and that it should be used as utf8.

However if I use utf8 i'm not able to write a sentence in Hebrew.

Another thing I tried is as following by using XeLatex:

\documentclass[]{article}
\usepackage{fontspec}
\setmainfont{Times New Roman}
\setsansfont{Arial}
\usepackage{polyglossia}
\setdefaultlanguage{hebrew}
\usepackage[sorting=none]{biblatex}

\begin{document}

\section{hello}
{\bfseries hello:}

Hebrew: מה הבעיה?

\medskip
\end{document}


However still error.

Is there a solution to be able to write in Hebrew and to insert bib file?

Thank you.

You can't use ucs. So either you switch to an unicode engine line xelatex or lualatex. Or you declare the missing unicode chars for utf8 like this:

\documentclass[a4paper, 12pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{culmus}
\usepackage[english,hebrew]{babel}

\pdfmapfile{=culmus.map}

\DeclareUnicodeCharacter{05E9}{\hebshin}
\DeclareUnicodeCharacter{05DC}{\heblamed}
\DeclareUnicodeCharacter{05D5}{\hebvav}
\DeclareUnicodeCharacter{05DD}{\hebfinalmem}
% and more

\begin{document}

\Large{שלום}

\end{document}


You can find the command names in he8enc.def.

• I added another thing that I tried without utf8x and used XeLatex however it also not working. – Ben Aug 16 '18 at 18:04
• How to get it working with xelatex/lualatex is quite a different question. Search the site for answers, e.g. tex.stackexchange.com/questions/434549/… – Ulrike Fischer Aug 16 '18 at 18:10
