chinese comments in utf-8 partly are changed when cubeMX regenerates the code
there is a strange phenomenon. I write some chinese comments in main.c and other files. when I use cubeMX to regenerate the code. the comments in main.c are partly changed and can't be display correctly. but the comments in the file that don't be regenerated by cubeMX are correct and don't be changed.

then I regenreate the codes by stm32cubeMX.

the mistake happend. I use the defualt configuration. but when I set encoding with GBK. the problem disappears.
