wchar_t is still around (although char8_t and std::u8string are the new 
hotness), it's just the conversion functions that are deprecated.  I 
guess you're just not supposed to convert anything any more.

More seriously, AFAIK there's no plans to actually remove it 
until/unless an actual replacement gets standardised.  But I think in 
the meantime they'd rather you use something like the ICU library for 
conversions instead.

Although it wouldn't surprise me if, in not wanting to take a dependency 
on an external library (and not wanting to continue using an officially 
deprecated standard function), a lot of libraries/apps will write their 
own subtly-broken conversion routines instead...
