I am currently using Low Replace to clean up content exported from EE to be used as a JSON object. This means cleaning up new lines, spaces, escaping quotes and backslashes. I am able to get the first three to work. However I cannot seem to find a way to escape a backslash.
I've even tried to map it as a replacement option in pi.low_replace.php
private $_map = array(
'SPACE' => ' ',
'QUOTE' => '"',
'NEWLINE' => "\n",
'PIPE' => '|',
'BACKSLASH' => "\\"
);
No luck.
