XMLSERIALIZE ignore INDENT parameter when use with ENCODING parameter together

For example:

SELECT XMLSERIALIZE(DOCUMENT xmltype('<data><a><b>111</b></a><c><d>222</d></c></data>') AS BLOB ENCODING 'UTF-8' INDENT SIZE=5) FROM dual

The BLOB content looks like

<?xml version="1.0" encoding="UTF-8"?>
<data>
<a>
<b>111</b>
</a>
<c>
<d>222</d>
</c>
</data>

There is no INDENT despite the fact that of using "INDENT SIZE=5" parameter in the statement.

although, executing the statement but without "ENCODING 'UTF-8'" parameter:

SELECT XMLSERIALIZE(DOCUMENT xmltype('<data><a><b>111</b></a><c><d>222</d></c></data>') AS BLOB INDENT SIZE=5) FROM dual

The BLOB content looks like
<data>
<a>
<b>111</b>
</a>
<c>
<d>222</d>
</c>
</data>

an INDENT exist before xml elements.

There is no indentations in the output xml file when using INDENT parameter along with ENCODING parameter.
