Constant to be used in the UnicodeString(char *, int32_t, EInvariant) constructor which constructs a Unicode string from an invariant-character char * string.
<p>
About invariant characters see <a class="el" href="utypes_8h.html">utypes.h</a>. This constructor has no runtime dependency on conversion code and is therefore recommended over ones taking a charset name string (where the empty string "" indicates invariant-character conversion).<p>
