|
In particular, opening and closing |
|
.Sq single quotes |

.Xr roff 7 |
|
formatters represent single quotes in ASCII output. |
|
This correct ASCII rendering may look strange with modern |
|
Unicode-compatible fonts because contrary to ASCII, Unicode uses |
|
the code point U+0060 for the grave accent only, never for an opening |
|
quote. |
