Android NDK Dev Guide(from NDK)
USING THE ANDROID TOOLCHAIN AS A STANDALONE COMPILER
5.2/ wchar_t support:
- - - - - - - - - - -
As documented, the Android platform did not really support wchar_t until
Android 2.3. What this means in practical terms is that:
- If you target platform android-9 or higher, the size of wchar_t is
4 bytes, and most wide-char functions are available in the C library
(with the exception of multi-byte encoding/decoding functions and
wsprintf/wsscanf).
- If you target any prior API level, the size of wchar_t will be 1 byte
and none of the wide-char functions will work anyway.
We recommend any developer to get rid of any dependencies on the wchar_t type
and switch to better representations. The support provided in Android is only
there to help you migrate existing code.
