Write delimited file with BOM

FrancoisSmfy — Sat, 16 Nov 2024 07:53:29 GMT

Hello,

I need to write a file in UTF16-LE with BOM, but the default tFileOutputDelimited component doesn't offer this possibility.

I test a custom component (tWriteHeaderLineToFileWithBOM) but get an error when I execute the processus (see below).

Did you have a way to easily add the BOM to such a file? With a component or a working java code?

Hello
Here is a related topic that introduces how to use this custom component.

Hope it helps!

Thanks, but even if I follow the explanations post in this thread, I always get the same error message post above.

To workaround this issue, I've created a static header file with BOM that I copy and rename in the output directory. Appending records to the existing header preserves the BOM.
