Comment 2 for bug 1615222

I spoke with a colleague at work, who also recently upgraded to 16.04 and regularly uses a Czech keyboard. He did not encounter this problem. I see now in the keyboards menu in the toolbar (top right) > Text Entry Settings, that there are now 6 options for a Czech keyboard. The original one I was using was the first one "Czech". I tried the different input sources and found that Czech (UCW layout, accented letter only), provides the correct key combinations. Ť ď ó for example, but this is not the classic qwertz keyboard, which should also provide Ť ď ó not (now switched to "Czech" ) ˇT ˇd ´o.

Checking the other Czech input sources with a simple editor like GVIM, none of them seem to work with ˇ or ´. Dvorak keyboards I've never used.
