I have a XeLaTeX document with lower half brackets ⸤⸥
(U+2E24,U+2E25) and upper half brackets ⸢⸣
(U+2E22,U+2E23). In the log file I get the complaint like Missing character: There is no ⸤ in font...
when I use Gentium or FreeSerif. However, in other contexts (Gnome Terminal, LibreOffice) these characters show up in those fonts. How can I get these characters to appear in my document?
\documentclass[12pt,letterpaper]{article}
\usepackage{xltxtra}
\setmainfont[Mapping=tex-text]{FreeSerif}
\begin{document}
\paragraph{} These are ⸤lower half-brackets⸥. These are ⸢upper half-brackets⸣.
It seems that other symbols work—such as ê.
\end{document}
Relevant portion of the log file:
Missing character: There is no ⸤ in font Free Serif/ICU:mapping=tex-text,!
Missing character: There is no ⸥ in font Free Serif/ICU:mapping=tex-text,!
Missing character: There is no ⸢ in font Free Serif/ICU:mapping=tex-text,!
