    Thank you. As I suspected, it's an encoding issue. The file is UTF-8, whereas OneStream largely reasons in UTF-16 (traditional default in Windows/.Net world). There are two ways to fix this, as far as I can see:

    • just convert the file to UTF-16 before uploading it, for example with Notepad++, or
    • turn the file bytes back to string and then from there to UTF-16 bytes using the Encoding classes.

    Here's some (untested) code that should send you in the right direction:

     

    ' at the top
Imports System.Text

[...]

' get the encodings we need
Dim utf8 As Encoding = encoding.UTF8
Dim utf16 As Encoding = Encoding.Unicode
' turn original bytes into String ...
Dim text As String = utf8.GetString(fileinfo.XFFile.ContentFileBytes)
' ... and from there to UTF16 bytes
Dim toUpload As Byte() = utf16.GetBytes(text)
' upload utf16 bytes
BRApi.Utilities.LoadCustomTableUsingDelimitedFile(si, _
	SourceDataOriginTypes.FromFileUpload, filePath, _
	toUpload, _
	"|", "App", "LOAD_TABLE", "Merge", lfieldtokens, True)

Hi, I have uploaded the test file to WeTransfer. Let me know if I should share it via a different method. Thank you
