RFR: 8268457: XML Transformer outputs Unicode supplementary character incorrectly to HTML

[Masanori Yano]

Hi all,

Could you please review the 8268457 bug fixes?

The problem is that ToHTMLStream applies processing for non-surrogate pairs to the surrogate pair.
This fix changes the processing for non-surrogate pairs to the else condition.
