Hi, thats OK for words in english, but in spanish don’t. Try to convert: documentación, gané, or other word with á, é, í, ó or ú.

Bye.

Of course, you’ll abuse *your* privilege to refuse my comment, nevertheless I have rigth to convey the truth: this is just a crap in all aspects.

Do meditate on the following –

// this stuff is Public Domain 😀
std::wstring string2wstring(std::string & str) {
return std::wstring(str.begin(),str.end());
}

Though this does NO conversion (like yours) but at last with no overhead 😉

Nothing personal, I’m able to code even worse, but taking care no one can watch it. Please do not confuse teaching and learning.

WBR, Serge.
