Text is correct. The same letter is opened correctly in RC on my test server. Both servers works with the same mail base and mail server.
Both have the same PHP and modules? You might also compare user Preferences > Displaying Messages > Default Character Set (in Advanced options section).
By the way, whether can two RCube on different servers use the same SQL base (Postgres)?
Sure you can, but on a working system it might be hard to switch. There should be no problems if you start with empty database.
In RoundCube log. In Apache error log there are many notices like this: [notice] child pid 2315 exit signal Segmentation fault (11) and nothing else.
That's it. In most such cases this is caused by some PHP bug. It's hard to investigate these.
