Query related to i18n characters handling in C language

Question

I have an nfs share mounted on both Windows and Linux both, I created a folder named "PRàjààjààjà" from Windows file explorer. When I do "ls /SomeFolder/MountedDir" in linux I see that folder in below named format

"'PR'$'\340''j'$'\340\340''j'$'\340\340''j'$'\340'"

Now In Linux side I am using FTW callback function where I print the full path of folder and it doesn't print correctly.

int ftw(const char *path, int (*fn)(const char *,
       const struct stat *ptr, int flag), int ndirs);

I assume that the callback function gives me in utf8. I have limited understanding here. Please help!

Expecting some answer to have same behaviour on Linux as well as Windows
