PL/SQL Developer shows carriage return + line feed where there is just a line feed in the data.
Easiest way to reproduce:
If you inspect the results in the built-in HEX viewer in PL/SQL Developer, you can see 0D 0A, which is CR + LF.
Apparently PL/SQL Developer adjusts the line breaks to be able to show the text properly (the single line feeds would otherwise probably be ignored in Windows), but the HEX view should display the actual data rather than a corrected version.
