[SOLVED] ReadCSV escape characters disappear even when quotes disabled

If the ReadCSV operator's "use quotes" parameter is off, the "escape character for quotes" parameter is hidden. This suggests that the "escape character for quotes" is only relevant when "use quotes" is on.

However, even with "use quotes" off, my ReadCSV operator seems to be removing '\' characters from the read content, unless I set "escape character for quotes" to some other character.

 <operator activated="true" class="process" compatibility="5.3.005" expanded="true" name="Process">

    We have renamed the parameter ("escape_character") and removed the parameter dependency (i.e. the parameter is always displayed) to make clear that this character will not only be used for quotes. The next release will contain these changes.
