Outputting Unicode characters
Orthogonal to the ability to include Unicode characters in a LATEX input file is the ability to include a given
Unicode character in the corresponding output file. By far the easiest approach is to use XE LATEX instead of
pdfLATEX or ordinary LATEX. XE LATEX handles Unicode input and output natively and can utilize system fonts
directly without having to expose them via .tfm, .fd, and other such files. To output a Unicode character,
a XE LATEX document can either include that character directly as UTF-8 text or use TEX’s \char primitive,
which XE LATEX extends to accept numbers larger than 255.
Suppose we want to output the symbols for versicle (“ ”) and response (“ ”) in a document. The Unicode
charts list “versicle” at position U+2123 and “response” at position U+211F. We therefore need to install a
font that contains those characters at their proper positions. One such font that is freely available from CTAN
is Junicode Regular (Junicode-Regular.ttf) from the junicode package. The fontspec package makes it easy
for a XE LATEX document to utilize a system font. The following example defines a \textjuni command that
uses fontspec to typeset its argument in Junicode Regular:
\documentclass{article}
\usepackage{fontspec}
\newcommand{\textjuni}[1]{{\fontspec{Junicode-Regular}#1}}
\begin{document}
We use ‘‘\textjuni{\char"2123}’’ for a versicle
and ‘‘\textjuni{\char"211F}’’ for a response.
\end{document}
which produces
We use “ ” for a versicle and “ ” for a response.
(Typesetting the entire document in Junicode Regular would be even easier. See the fontspec documentation
for more information regarding font selection.) Note how the preceding example uses \char to specify a
Unicode character by number. The double quotes before the number indicate that the number is represented
in hexadecimal instead of decimal.
8.8 About this document
History David Carlisle wrote the first version of this document in October, 1994. It originally contained
all of the native L ATEX symbols (Table 44, Table 57, Table 67, Table 102, Table 128, Table 131, Table 152,
Table 153, Table 164, Table 169, Table 201, and a few tables that have since been reorganized) and was designed
to be nearly identical to the tables in Chapter 3 of Leslie Lamport’s book [Lam86]. Even the table captions
and the order of the symbols within each table matched! The AMS symbols (Table 45, Table 68, Table 69,
Table 105, Table 106, Table 132, Table 137, Table 148, and Table 202) and an initial Math Alphabets table
(Table 213) were added thereafter. Later, Alexander Holt provided the stmaryrd tables (Table 46, Table 59,
Table 70, Table 108, Table 125, and Table 149).
In January, 2001, Scott Pakin took responsibility for maintaining the symbol list and has since implemented
a complete overhaul of the document. The result, now called, “The Comprehensive L ATEX Symbol List”,
includes the following new features:
