On my system, gcc doesn't handle UTF-16 at all, with or without a BOM.
(I don't know whether there's a way to configure it to do so.)
It does handle UTF-8 with or without a BOM.
$ file b.cpp
b.cpp: C source, UTF-8 Unicode (with BOM) text
$ cat b.cpp
int main() { }
$ hd b.cpp
00000000 ef bb bf 69 6e 74 20 6d 61 69 6e 28 29 20 7b 20 |...int main() { |
00000010 7d 0a |}.|
00000012
$ gcc -c b.cpp
$
gcc 9.3.0 on Ubuntu 20.04. (There is, of course, no point in going back
to ancient versions of gcc.)
