<p>Very simple string class with some useful features. </p>
<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>
<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. </p>
