This appears to be related to this discussion but I have exactly the opposite use case. I do not wish to insert a BOM but
emacs appears to be inserting one in XML mode (without even being in
hexl-mode). I am using GNU Emacs 23.3.1.
I have the following XML file:
$ cat a.xml <?xml encoding="UTF-16"?><a/> $ xxd a.xml 0000000: 3c3f 786d 6c20 656e 636f 6469 6e67 3d22 <?xml encoding=" 0000010: 5554 462d 3136 223f 3e3c 612f 3e0a UTF-16"?><a/>.
The file does not contain a BOM as can be seen.
When I try to open it with
emacs a.xml this is what I see:
When I then switch to
hexl-mode it appears that a BOM has been inserted:
This happens even if I start Emacs with
