• Although “/” does not require any special treatment, L ATEX additionally defines a \slash command
which outputs the same glyph but permits a line break afterwards. That is, “increase/decrease” is
always typeset as a single entity while “increase\slash{}decrease” may be typeset with “increase/”
on one line and “decrease” on the next.
• \textasciicircum can be used instead of \^{}, and \textasciitilde can be used instead of \~{}.
Note that \textasciitilde and \~{} produce raised, diacritic tildes. “Text” (i.e., vertically centered)
tildes can be generated with either the math-mode \sim command (shown in Table 67 on page 30),
which produces a somewhat wide “∼”, or the textcomp package’s \texttildelow (shown in Table 40
on page 20), which produces a vertically centered “~” in most fonts but a baseline-oriented “” in
Computer Modern, txfonts, pxfonts, and various other fonts originating from the TEX world. If your
goal is to typeset tildes in URLs or Unix filenames, your best bet is to use the url package, which has a
number of nice features such as proper line-breaking of such names.
• The various \char commands within \texttt are necessary only in the OT1 font encoding. In other
encodings (e.g., T1), commands such as \{, \}, \_, and \textbackslash all work properly.
• The code page 437 (IBM PC) version of ASCII characters 1 to 31 can be typeset using the ascii package.
See Table 227 on page 72.
• To replace “‘” and “’” with the more computer-like (and more visibly distinct) “`” and “'” within
a verbatim environment, use the upquote package. Outside of verbatim, you can use \char18 and
\char13 to get the modified quote characters. (The former is actually a grave accent.)
Similar to Table 328, Table 329 on the next page is an amalgamation of data from other tables in this
document. While Table 328 shows how to typeset the 7-bit ASCII character set, Table 329 shows the Latin 1
(Western European) character set, also known as ISO-8859-1.
The following are some additional notes about the contents of Table 329:
• A “(tc)” after a symbol name means that the textcomp package must be loaded to access that symbol.
A “(T1)” means that the symbol requires the T1 font encoding. The fontenc package can change the
font encoding document-wide.
• Many of the \text. . . accents can also be produced using the accent commands shown in Table 17 on
page 14 plus an empty argument. For instance, \={} is essentially the same as \textasciimacron.
• The commands in the “L ATEX 2ε” columns work both in body text and within a \texttt{. . .} command
(or, more generally, when \ttfamily is in effect).
• The “£” and “$” glyphs occupy the same slot (36) of the OT1 font encoding, with “£” appearing in italic
fonts and “$” appearing in roman fonts. A problem with L ATEX’s default handling of this double-mapping
is that “{\sffamily\slshape\pounds}” produces “$”, not “£”. Other font encodings use separate slots
for the two characters and are therefore robust to the problem of “£”/”$” conflicts. Authors who use
\pounds should select a font encoding other than OT1 (as explained on page 8) or use the textcomp
package, which redefines \pounds to use the TS1 font encoding.
• Character 173, \-, is shown as “-” but is actually a discretionary hyphen; it appears only at the end of
a line.
Microsoft ® Windows ® normally uses a superset of Latin 1 called “Code Page 1252” or “CP1252” for
short. CP1252 introduces symbols in the Latin 1 “invalid” range (characters 128–159). Table 330 presents the
characters with which CP1252 augments the standard Latin 1 table.
The following are some additional notes about the contents of Table 330:
• As in Table 329, a “(tc)” after a symbol name means that the textcomp package must be loaded to access
that symbol. A “(T1)” means that the symbol requires the T1 font encoding. The fontenc package can
change the font encoding document-wide.
• Not all characters in the 128–159 range are defined.
• Look up “euro signs” in the index for alternatives to \texteuro.
