Very simple <a class="el" href="classirr_1_1core_1_1string.html">string</a> class with some useful features.
<p>
string<c8> and string<wchar_t> both accept Unicode AND ASCII/Latin-1, so you can assign Unicode to string<c8> and ASCII/Latin-1 to string<wchar_t> (and the other way round) if you want to.<p>
However, note that the conversation between both is not done using any encoding. This means that c8 strings are treated as ASCII/Latin-1, not UTF-8, and are simply expanded to the equivalent wchar_t, while Unicode/wchar_t characters are truncated to 8-bit ASCII/Latin-1 characters, discarding all other information in the wchar_t. <dl compact><dt><b>Enumerator: </b></dt><dd>
