[Tex/LaTex] Option unicode=true with hyperref

hyperrefportabilityunicode

Is there a drawback when using the option unicode=true with the package hyperref and the engines PDFTeX, XeTeX and LuaTeX?

In other words, can a portable document always have \usepackage[unicode=true]{hyperref}?

As far as my experience goes, all reasonably recent versions of Adobe's PDF Reader, Gnome's Evince, and Mac OSX's Preview support unicode bookmarks.

The LuaTeX manual says quite clearly that \char now accepts values between 0 and 1114111 and extends this statement to the other similar commands like \lccode. As far as I know this is true in XeTeX too. And IMHO a command line to change this seems rather senseless.

But the eTeX extension can be disabled in both engines. Or more precisely: XeTeX has a command line option to enable the eTeX extension (which is used by default by all TeX Systems) and LuaTeX has a similar feature. So it is possible to build a format manually which doesn't use them. But this affects only the eTeX relevant commands.

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}
