Encoding special chars |
|
---------------------- |
|
|
|
The LaTeX Info pages lists under "2.18 Special Characters" |
|
|
|
The following characters play a special role in LaTeX and are called |
|
"special printing characters", or simply "special characters". |
|
|
|
# $ % & ~ _ ^ \\ { } |
|
|
|
The special chars verbatim:: |
|
|
|
# $ % & ~ _ ^ \ { } |
|
|
|
However also *square brackets* [] need special care. |
|
|
|
Commands with optional arguments (e.g. ``\item``) check |
|
if the token right after the macro name is an opening bracket. |
|
In that case the contents between that bracket and the following |
|
closing bracket on the same grouping level are taken as the |
|
optional argument. What makes this unintuitive is the fact that |
|
the square brackets aren't grouping characters themselves, so in |
|
your last example \item[[...]] the optional argument consists of |
|
[... (without the closing bracket). |
|
|
|
Compare the items in the following lists: |
|
|
|
* simple item |
|
* [bracketed] item |
|
|
|
simple |
|
description term |
|
|
|
[bracketed] |

The OT1 font-encoding has different characters for the less-than, |
|
greater-than and bar, < | >, except for typewriter font `cmtt`:: |
