The following accents may be placed on letters. Although "o" is used in
most of the example, the accents may be placed on any letter.
Accents may even be placed above a "missing" letter; for example,
\~{} produces a tilde over a blank space.
The following commands may be used only in paragraph or LR mode.
\`{o} produces a grave accent, ò
\'{o} produces an acute accent, ó
\^{o} produces a circumflex, ô
\"{o} produces an umlaut or dieresis, ö
\H{o} produces a long Hungarian umlaut
\~{o} produces a tilde, õ
\c{c} produces a cedilla, ç
\={o} produces a macron accent (a bar over the letter)
\b{o} produces a bar under the letter
\.{o} produces a dot over the letter
\d{o} produces a dot under the letter
\u{o} produces a breve over the letter
\v{o} produces a "v" over the letter
\t{oo} produces a "tie" (inverted u) over the two letters
Note that the letters "i" and "j" require special treatment when
they are given accents because it is often desirable to replace the
dot with the accent. For this purpose, the commands \i and
\j can be used to produce dotless letters.
