cannot open File with UTF-8 Name

[SWIPHER]

Hi, I'm trying to open a chinese name file like "你好.txt" but it doesn't work; and the major code is like: #define USE_UTF8_LONG_NAMES 1 /*And I also change the value of this in SdFatConfig.h*/ SdFs sd; FsFile music; sd.begin(SD_CS); music.open("你好.txt"); Looking forward for reply Thank you so much!

I have no idea what your problem is.

I added your filename to the UnicodeFilenames example like this. const char* names[] = {u8"你好.txt", u8"россиянин", u8"très élégant", u8"狗.txt", nullptr};

I set the following in the example and ran it on FAT16, FAT32, and exFAT.

// Remove files if non-zero.
#define REMOVE_UTF8_FILES 0

// SD_FAT_TYPE = 0 for SdFat/File as defined in SdFatConfig.h,
// 1 for FAT16/FAT32, 2 for exFAT, 3 for FAT16/FAT32 and exFAT.
#define SD_FAT_TYPE 3

The output is:

Type any character to begin

ls:
      131072 😀/
            12 你好.txt
            20 россиянин
            17 très élégant
             9 狗.txt
Done!

I can open the files on a PC and they have the correct content.
