This assumes that the wchar_t uses UTF-16 as its encoding. Therefore,
this will produce wrong results on non-windows platforms...
size_t size = wcstombs((char*)ptr.data(), wpr, 4096);
Err, this can return -1. You should handle that case, it's a quite real
possibility on windows, where the system charset tends to be only a
small subset of unicode.
(This also fails for strings larger than 4096 characters, and you could
avoid that by calling wcstombs with NULL as the first argument to get
the required size)
I have done this task in the same way. The mozilla strings guide advises
use only nsAString. The nsAString hasn’t got method for conversion. What
should I do? I have to use my own unsafe code.
