c++ easy way to convert macro variable to wchar string literal -

in next example, remove std::wstring(std::widen(...)) part, '#' macro returns char string literal -- there way accommodate wchar?

#define foo_macro(classname)\ struct classname##factory : public otherclass {\ // stuff here\ } classname##factory;\ somemap->add(std::wstring(std::widen(#classname), classname##factory)))

how same thing using wchar?

you utilize l prefix on string literal create wchar string literal:

#define cat(a, b) a##b #define wstring(a) cat(l, #a)

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
