The following must always be set to interpret the expression as a string
literal:
</p>
<div class="informaltable"><table class="table">
<colgroup>
<col>
<col>
<col>
</colgroup>
<thead><tr>
<th>
<p>
Element
</p>
</th>
<th>
<p>
Standardized
</p>
</th>
<th>
<p>
Effect when set
</p>
</th>
</tr></thead>
<tbody><tr>
<td>
<p>
literal
</p>
</td>
<td>
<p>
Yes
</p>
</td>
<td>
<p>
Treat the string as a literal (no special characters).
</p>
</td>
</tr></tbody>
</table></div>
<p>
The following options may also be combined with the literal flag:
</p>
<div class="informaltable"><table class="table">
<colgroup>
<col>
<col>
<col>
</colgroup>
<thead><tr>
<th>
<p>
Element
</p>

<p>
Standardized
</p>
</th>
<th>
<p>
Effect when set
</p>
</th>
</tr></thead>
<tbody>
<tr>
<td>
<p>
icase
</p>
</td>
<td>
<p>
Yes
</p>
</td>
<td>
<p>
Specifies that matching of regular expressions against a character
container sequence shall be performed without regard to case.
</p>
</td>
</tr>
<tr>
<td>
<p>
optimize
</p>
</td>
<td>
<p>
Yes
</p>
</td>
<td>
<p>
Specifies that the regular expression engine should pay more
attention to the speed with which regular expressions are matched,
and less to the speed with which regular expression objects are
constructed. Otherwise it has no detectable effect on the program
output. This currently has no effect for Boost.Regex.
