How to add BOM to UTF-8 file via BAT?

Question

cmd/bat

Good afternoon! I had a need to add a BOM header to a txt file, via bat. I would like to know how this can be implemented approximately.

Answer 1

Make the file containing the BOM, for example bom.txt, add like this:
copy /b /y bom.txt+file.txt file1.txt
Then file1.txt can be renamed.
