I'd like to remove Bite Order Masks from my
UTF-8 files in Intellij IDEA, how can I do this?
The problem is that if I'm trying to do it via other editors (e.g. Akelpad),
when I modify the file later in IDEA it somehow remembers that BOM
was present and adds it to my file again (((
There is no such action to remove BOM from UTF-8 files in IntelliJ IDEA. There was a bug that BOM is removed, but it was fixed a long time ago.
When you remove BOM externally, make sure the file is synchronized with editor, try File | Synchronize.
If IntelliJ IDEA still thinks that this file has BOM, please file an issue with the steps to reproduce.
