In output modes supporting such special output characters, for example |
|
.Fl T Cm pdf , |
|
some |
|
.Xr roff 7 |
|
formatters convert the following ASCII input characters to the |
|
following Unicode special output characters: |
|
.Bl -column x(ga U+2018 -offset indent |
|
.It \(ga Ta U+2018 Ta left single quotation mark |
|
.It \(aq Ta U+2019 Ta right single quotation mark |
|
.It \(ti Ta U+02DC Ta small tilde |
|
.El |
|
.Pp |
|
In prose, this automatic substitution is often desirable; |
|
but when these characters have to be displayed as plain ASCII |
|
characters, for example in source code samples, they require |
|
escaping to render as follows: |
|
.Bl -column x(ga U+2018 -offset indent |
|
.It \e(ga Ta U+0060 Ta grave accent |
|
.It \e(aq Ta U+0027 Ta apostrophe |

.It \e(ti Ta U+007E Ta tilde |
