EmbeddedDocumentBinaryObjectType value only Bytes() can't be String about ph-ubl

You don't need to Base64 encode yourself. In the code you provide the source binary content, and the Base64 encoding happens automatically in the background

does Base64 encode support StandardCharsets.UTF_8
because I encode Arabic char to hex then I encode it to Base64 UTF_8

It's suppose when I enter 012a416264756c6c61682048617373616e20416c2d4e617373657220476f6c6420436f72706f726174696f6e020F3331303132323339333530303030330314323032322d30342d32355431353a33303a30305a0407313030302e303005063135302e3030
it gave me
ASpBYmR1bGxhaCBIYXNzYW4gQWwtTmFzc2VyIEdvbGQgQ29ycG9yYXRpb24CDzMxMDEyMjM5MzUwMDAwMwMUMjAyMi0wNC0yNVQxNTozMDowMFoEBzEwMDAuMDAFBjE1MC4wMA==

But unfortunately it gave me another result

thinks I solve the issue

String originalInput="012a416264756c6c61682048617373616e20416c2d4e617373657220476f6c6420436f72706f726174696f6e020F3331303132323339333530303030330314323032322d30342d32355431353a33303a30305a0407313030302e303005063135302e3030";
HexBinaryAdapter adapter = new HexBinaryAdapter();
byte[] bytes = adapter.unmarshal(originalInput);
Emdb3.setValue(bytes );

the output is matched

Okay if the original String is already encoded (as in hex encoding in your example), then this needs to be considered separately. This is independent of Base 64 :)

Assume I have a String that contains German Umlauts, I need to explicitly use the character set when calling getBytes() as in this (untested) example:

String s = "Test äöü";
byte[] b = s.getBytes (StandardCharsets.UTF_8);
EmbeddedDocumentBinaryObjectType Emdb3 = new EmbeddedDocumentBinaryObjectType();
Emdb3.setMimeCode("text/plain");
Emdb3.setValue(b);

How you get your raw "byte[]" is up to you and you need to know what to do, And the difference between char and byte might be confusing when dealing with these issues for the first time.....
