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.
