[tex-live] Issue with \textgreater and lualatex

[jfbu]

Hi,

apologies if wrong list, but I am online for a short wile and
wasn't sure where to post.

This MWE

\documentclass{article}

\ifdefined\directlua
\usepackage{fontspec}
\else
\ifdefined\XeTeXinterchartoks
\usepackage{fontspec}
\else
\usepackage[T1]{fontenc}
\fi\fi

\begin{document}
% uniquement avec lualatex donne »
\textgreater{}\textgreater{}

% ici aussi donne »
{\textgreater}{\textgreater}

\end{document}


produces similar result with pdflatex and xelatex
but not with lualatex which applies a ligature.

Surely this has been raised somewhere, but is there
a fix in mark-up which would be engine independent.

This is a real life issue arising in indexing of
Python's >>> prompt with the > being escaped into
TeX macro \textgreater{} by some documentation
production tool, and then LuaLaTeX gives bad result.

Best,

Jean-François
