A wide character. In-memory only. ?-bit fixed-width representation of the platform's natural wide character set. Could be different sizes on different platforms.

An 8-bit character type. In-memory only. 8-bit representation. Should really be char8_t but making this the generic option is easier for compilers which don't fully support C++11 yet (i.e. MSVC).

A 32-bit character type. In-memory only. 32-bit representation. Should really be char32_t but making this the generic option is easier for compilers which don't fully support C++11 yet (i.e. MSVC).

A 16-bit character type. In-memory only. 16-bit representation. Should really be char16_t but making this the generic option is easier for compilers which don't fully support C++11 yet (i.e. MSVC).

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
