Unicode Regular Expression Algorithms</a></h5></div></div></div>
|

<p>
|

The regular expression algorithms <a href="../../regex_match.html" title="regex_match"><code class="computeroutput"><span class="identifier">regex_match</span></code></a>, <a href="../../regex_search.html" title="regex_search"><code class="computeroutput"><span class="identifier">regex_search</span></code></a> and <a href="../../regex_replace.html" title="regex_replace"><code class="computeroutput"><span class="identifier">regex_replace</span></code></a> all expect that
|
||||
the character sequence upon which they operate, is encoded in the same
|
||||
character encoding as the regular expression object with which they are
|
||||
used. For Unicode regular expressions that behavior is undesirable: while
|
||||
we may want to process the data in UTF-32 "chunks", the actual
|
||||
data is much more likely to encoded as either UTF-8 or UTF-16. Therefore
|
||||
the header <boost/regex/icu.hpp> provides a series of thin wrappers
|
||||
around these algorithms, called <code class="computeroutput"><span class="identifier">u32regex_match</span></code>,
|
||||
<code class="computeroutput"><span class="identifier">u32regex_search</span></code>, and
|
||||
<code class="computeroutput"><span class="identifier">u32regex_replace</span></code>. These
|
||||
wrappers use iterator-adapters internally to make external UTF-8 or UTF-16
|
||||
data look as though it's really a UTF-32 sequence, that can then be passed
|
||||
on to the "real" algorithm.

|

defines an overloaded algorithm that takes the same arguments, but which
|
||||
is called <code class="computeroutput"><span class="identifier">u32regex_replace</span></code>,
|
||||
and which will accept UTF-8, UTF-16 or UTF-32 encoded data, as well as
|
||||
an ICU UnicodeString as input. The input sequence and the format string
|
||||
specifier passed to the algorithm, can be encoded independently (for
|
||||
example one can be UTF-8, the other in UTF-16), but the result string
|
||||
/ output iterator argument must use the same character encoding as the
|
||||
text being searched.

here they are anyway:

TCHAR, then use the regular Boost.Regex types <code class="computeroutput"><span class="identifier">regex</span></code>
|

and <code class="computeroutput"><span class="identifier">wregex</span></code> instead.
