What whitespace symbols does Winmerge use for line endings (EOF and EOL)?

Question

If I select View Whitespace from the view menu of WinMerge, line-ending symbols are displayed. One file has been changed, but I can't find any documentation on what symbols represent what characters.

No idea what this pair of symbols signifies, this is the file before line-ending conversion to CR/LF:

This symbol seems represent the CR/LF pair, as I converted the file to have those line endings:

To add some more context, Visual Studio detected that this file had mixed line endings, and converted them to CR/LF. Then I looked at the differences to the original file stored in git. So gits line-ending conversion may have some interaction here in the way it converts the original file. My line endings are for automatically changing to windows line endings.

WinMerge 2.14.0.0 Unicode (and probably other versions as well) has a setting under menu://edit/options/Editor "preserve original EOL characters".

• When "preserve original EOL characters" is checked WinMerge shows §¶ for some files and ¶ for others¹.
• When "preserve original EOL characters" is unchecked, WinMerge shows ¤.
  Note: unchecked "preserve original EOL characters" can cause WinMerge to mark two files, that appear identical, as having differences on every line.

Using a hexeditor shows that:

• 0x0d a.k.a. <cr> is shown as §; and
• 0x0a a.k.a. <lf> is shown as ¶.
