dataset AddOrUpdate not find Encod args about fo-dicom

version fo-dicom 5.1.2

The encoding should be done using the dataset encoding, taken from SpecificCharacterSet. If the character set cannot encode this string, it will get garbled. What encoding is set in your dataset?

I can set the SpecificCharacterSet property to display normally, but in the previous version 4.0, AddOrUpdate was able to set character sets, so why not now.

4.0 code:
public DicomDataset AddOrUpdate(DicomTag tag, Encoding encoding, params T[] values)
{
return DoAdd(tag, encoding, values, allowUpdate: true);
}

The version of for-dicom v5 no longer has this encoding parameter

An encoding parameter for an individual item does not make much sense, because all items must be encoded with the dataset encoding according to SpecificCharacterSet. Setting the encoding for an item to another value would produce invalid DICOM. I guess this was the reason it was removed.
If you have set SpecificCharacterSet in your dataset, and your data is still encoded incorrectly, then this may be a bug. See also my last comment in #1785.

Understood, thank you!
