Hi Elliot,
Same problem here, and probably in many websites with computer/Internet related content – windows paths, windows registry keys, latex markup, some regular experessions, code snippets with escaping sequences are destroyed if someone uses ACF WYSIWYG to store them.
Not to mention ASCII arts! :-))
Solution mentioned by figureone seems fine for me also.
Any plans for fix in near future?
Thanks in advance
Marek
