--> https://bugs.winehq.org/attachment.cgi?id=57728
working example, should link msvcrt.dll (e.g. use mingw to compile)
(1) assume test.txt has this content
hexdump -C test.txt
00000000 ef bb bf 68 65 6c 6c 6f |...hello|
00000008
// the content is UTF8 BOM + "hello"
(2) fscanf(fp, "\xef\xbb\xbf") doesn't work as expected (using crossover
16.2.0)
char s[1000];
fscanf(fp, "\xef\xbb\xbf"); ///// won't read utf-8 bom as expected
fscanf(fp, "%s", s);
/opt/cxoffice/bin/wine test.exe | hexdump -C
00000000 73 3d ef bb bf 68 65 6c 6c 6f 0d 0a |s=...hello..|
0000000c
(3) expected behavior is (under windows)
E:\winebug>test2
s=hello
