Here's the problem. Up to now I've only made incidental use of XDebug. Mostly because it was a pain to find a stable combination of editor and plugin in which it worked consistently.
And along came NetBeans, however, I find that it is incapable of switching file encoding on the fly. It applies the setting project wide. So when opening a file that is not UTF8 encoded, it causes a warning and if continuing, the ansi representation of accented characters gets destroyed. Since most of these occur in the author name, that is in itself not a big deal, easy to fix. It's gonna be a pain though keeping them UTF8 encoded when pulling updates from original COPS.
So why use UTF8? Well, since the wish came to be able to search, sort or group without accented characters not being found, sorted out of order or grouped separately, this means at least one file requires to be UTF8 encoded. And because of stupid NetBeans only applying this project wide all files need to use same encoding.
Since I've wasted a lot of time already trying to get Eclipse to work with XDebug, and now finding that its a breeze using it in NetBeans, I am not inclined to start hunting again so conversion to UTF8 is then the simplest alternative.
