Oxygen XML Editor lets you configure which Unicode space characters are treated as space characters when normalizing whitespace in XML documents. To configure the Whitespace preferences, open the Preferences dialog box and go to .
This table lists the Unicode whitespace characters. Check any that you want to have treated as whitespace when formatting and indenting an XML document.
The characters with the codes 9 (TAB), 10 (LF), 13 (CR) and 32 (SPACE) are always considered to be whitespace characters and cannot be deselected.
