I think changing the LilyPond parser to support BOM in the middle (ie not at the beginning) of the file is very hard. Actually if it is not at the beginning, then it should be treated as a regular character, which might not be present just anywhere in the file.

Why would that be? Did you not have a Flex generated .l file? If the input .l file is in UTF-8 and Flex in 8-bit mode, add a rule
  "<BOM>" {}
where <BOM> is the UTF-8 representation of the BOM. It will than add act as space, breaking tokens, but otherwise ignored. So it acts a zero-width space.
