Sorry but for the moment I’ll raise more questions than I’ll answer them
I just upgraded one of my websites from 0.9.5 to 0.9.6RC2.
Strange stuff happened at first (when I clicked any manager menu item, the "main" frame was opened full screen and I lost both menu and tree frame

). I cleaned cookies, session and cache from my browser and everything got back to normal.
But the strangest thing happens when I set manager language and character encoding : while the french language file is correctly encoded as utf-8, accents get displayed as question marks ( ? ) instead. I noticed along the way there was a misnamed duplicate in language file (francais-utf-8.inc.php -> older plus francais-utf8.inc.php -> last updated).
Anyway, back to the issue :
1. I re-checked encoding, nuked language file and re-uploaded it (just to be sure) -> no changes. Also made sure the Manager HTML and XML Language Attribute is set to "fr". When I cheked all frames source code charset is UTF-8 and xml language is "fr"...
2. I thought there was a problem uploading MODx files on upgrade, thus I re-uploaded the whole manager directory (since it seems to come from here). No improvement.
3. I checked both config.inc.php and the modx_site_settings table : just noticed the old etomite_charset table was still there and with the bad charset : changed it to UTF-8 just to be sure. But then did a clean 0.9.6 RC2 install, checked for tables there and found out there was no etomite_charset table anymore (correct me if I am wrong). I nuked the old etomite_charset table. No changes. Also noticed The site ID was not identical between config.inc.php and the database : corrected it. No change.
Now I would have understood if I had charset problems with the website’s content since it has been converted from latin1 to utf-8 but content has no issue whatsoever, it’s the character display in the manager that does not work. The clean 0.9.6 RC2 install I did works just fine so it’s definitely not the language file encoding which is at fault. Also, funniest thing is, I did an upgrade from 0.9.5 to 0.9.6RC1 on the same server and I didn’t experience this problems
I’ll keep on digging but if you have an idea...
