Hi,
test.c is a part of my test code about freetype2, which is indeed incomplete,
but could you put the functions in test.c into your project and run the test
function.
1.Call the test() function in your project's mian() function.
2.ff_convert() can be commented out and ignored.
3._T() depends on whether the string used by the file system is utf-16 or utf-8.
I have fully supplemented test.c
Thank you??

I'm unsure whether this is really the code that you tested.
Attached test.c is not buildable, because of following problems.
1) test.c has no main() function.
2) test.c includes no header files. no freetype header file, no standard C
header file (like stdint.h to use uint16_t)
3) test.c is not self-standing code, it calls some external functions or
macros. _T(), ff_convert() are not defined.
