This panel displays the special whitespace characters of Unicode. Any character that is
checked in this panel is considered whitespace that can be normalized in an XML document. The
whitespaces are normalized by the following actions:
- when the action Format and Indent is applied on an XML
document
- when you switch from Text mode to Author mode
- when you switch from Author mode to Text mode
The characters with the codes 9, 10, 13 and 32 are always in the group of whitespace
characters that must be normalized so they are always enabled in this panel.
