[Tex/LaTex] Using the `geometry` package with luatex

geometryluatex

According to the geometry package's user manual (2010/09/12 v5.6, section 5.6 'Drivers', p. 11)

The package supports drivers dvips, dvipdfm, pdftex, xetex, and vtex.

Can I use this package with luatex? If so – which driver should I specify? If not – what are the alternatives?

Best Answer

As with graphics and color it is usually best not to specify a driver at all and let the system detect what you are using. Unfortunately however geometry has not been updated to luatex 0.85 and later so you need to use

\RequirePackage{luatex85}

as the first line of the document to offer a compatibility layer, geometry will then work using the pdftex driver files.

luatex85 is no longer required with geometry 2018/03/24 v5.7

I think we don't need to do much. The only incompatible thing I know is the UTF-8 encoding.

To answer the sub-questions:

Any package related to input encodings and font encodings:
- inputenc. You should always use UTF-8 encoding to input the text. For backward compatibility, use luainputenc instead.
- fontenc. Don't use it with fontspec explictly.
- textcomp. Use xunicode instead, which is loaded by fontspec.
- Most old font packages (esp. for text fonts) are better not to be used. For example, use XITS, TeX Gyre Termes or Linux Libertine O fonts with fontspec instead of times package, and use Unicode fonts for main text together with mathptmx and txfonts (font math fonts only) to get proper text fonts.
- CJK is not compatible with LuaTeX. Today only a few unofficial LaTeX packages in Korea and Japan are available. This may be not very important for western users.
fontspec. To load TrueType/OpenType fonts. This is the only necessary one, I think. Also, luacode and unicode-math are useful.

At first you should imho better use utf8 instead of utf8x. utf8x is unmaintained and has problems e.g. with biblatex. (You will have to set up the some missing definitions for pdflatex). You will also have to add some definitions for lualatex as it will map - as you already found out - undeclared chars simply to their unicode position. Here e.g. two definitions for ½ & µ:

\documentclass{article}
\usepackage[utf8]{luainputenc}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\renewcommand{\rmdefault}{lmr}
\DeclareUnicodeCharacter{00BD}{\textonehalf}
\DeclareUnicodeCharacter{00B5}{\textmu}
\begin{document}
\begin{tabular}{@{}l*{10}{p{7mm}@{}}}
Some T1 characters:     & \# & \$ & \% & Ă & Ň & § & @ & Æ & ß   & £   \\[1.5mm]
Some non-T1 characters: & ‡  & ÿ  & ‰  & … & ¶ & ½ & µ %ĩ &  & | | & | | \\    \end{tabular}
\end{document}
