So, this doesn't look like an issue at all with Lucene.NET. You are specifying `Encoding.UTF8`. In .NET Framework, when you do that you get `UTF8Encoding(true)` - which emits a BOM. https://github.com/microsoft/referencesource/blob/master/mscorlib/system/text/encoding.cs#L1549 In .NET Core, they changed it to be the same as `Encoding.Default`, which creates a `UTF8Encoding` instance without a BOM. Presumably, this is to match the default behavior of Java. https://github.com/dotnet/runtime/blob/v6.0.26/src/libraries/System.Private.CoreLib/src/System/Text/Encoding.cs#L1071 https://github.com/dotnet/runtime/blob/v6.0.26/src/libraries/System.Private.CoreLib/src/System/Text/Encoding.cs#L80-L83 In short, if you want encoding without a BOM, you have to specify it that way. On .NET Framework, you have to call the constructor and pass `false` for the `encoderShouldEmitUTF8Identifier` parameter. ```c# var utf8NoBOM = new UTF8Encoding(encoderShouldEmitUTF8Identifier: false); ``` https://learn.microsoft.com/en-us/dotnet/api/system.text.utf8encoding.-ctor?view=net-8.0#system-text-utf8encoding-ctor(system-boolean) -- This is an automated message from the Apache Git Service.
