toAscii() in Qt5

[TorAn]

I am looking for a suitable replacement of toAscii(), since it is deprecated in Qt5.

Is

QString str("test");
const char* ptr = (const char*) (str.utf16());

QString str("test");
const char* ptr = (const char*) (str.utf16());

To copy to clipboard, switch view to plain text mode 

a good substitute for toAscii()?

Advise/comment is appreciated, thanks.
