How can I select UTF-8 with BOM?

[DemoCrazer]

I want to change UTF-8 to UTF-8 with BOM through "Reopen with Encoding", but I couldn't find UTF-8 with BOM.
I added "files.encoding": "utf8bom" into Preference file but it doesn't work.
How can I select UTF-8 with BOM?

@Luberen to be clear you want to add a BOM to a document?

[DemoCrazer]

@bpasero yes I want to add BOM to the document.

[bpasero]

@Luberen then just pick "Save with Encoding" instead of "Reopen with Encoding".

[DemoCrazer]

@bpasero I can't find UTF-8 with BOM in there.

@bpasero Oh, I tried to find in 'Reopen' with Encoding. Why are they different?
Anyway I set UTF-8 BOM now. Thanks

[bpasero]

@bpasero they are different, the one reopens with encoding and the other saves with encoding?
