-//! Very simple string class with some useful features.
-/** 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.
-
-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.
