Yes, it uses a goto statement. Even though goto statements are considered harmful, I think it is okay in this situation.

Since the implementation of this is the issue, I think the problem can be fixed more easily by changing this only.
Something like..
unsigned char file_head[3];
read_size = fread(file_head, 1, 3, file);
if (read_size == 3 && memcmp(file_head, utf8_endian_mark, sizeof(file_head)) == 0) {
// Skip UTF-8 BOM
size -= sizeof(file_head);
} else {
// Read data needs to be retained
rewind(file);
}

Thanks, I will incorporate that into a new commit.

I'd also recommend adding a test for this, but that might not be easy to do since our tests are set up to have metadata in the input file. |
