Write BOM
Mp3tag exports data in Unicode format encoded as UTF-8 by default. This option enables writing of a Byte Order Marker which is required by some applications.
Initially I used UTF-8 as default but changed that due to many "Bug Reports" caused by third-party applications not supporting UTF-8 files. Obviously, I forgot to update the corresponding topic in the help.
Write BOM
If you enabled writing of UTF-8 or UTF-16 via the $filename function in the export configuration, this option enables writing of a Byte Order Marker which is required by some applications.
