Keyboard input testing report for 8u20

[Anthony Petrov]

In the past few days I've tested how well FX supports international 
keyboard layouts. I've tested EN, DE, FR, RU, and JP keyboard layouts. 
Note that myself, I only speak EN and RU, so I might have missed some 
uncommon (or even some common) cases when trying to enter characters in 
other languages.

MS Windows:
Everything works as expected. I've tested all known (to me) dead keys in 
all the keyboard layouts, and they produce expected results, allowing 
users to enter all the characters that they want.

Mac:
JavaFX supports international keyboard layouts on Mac somewhat poorly. 
Using dead keys on European keyboards may result in inserting two 
characters when only one is expected. On the bright side, though, JP 
input seems to work just fine. Also, it's a known issue (RT-35074) that 
OEM keys generate wrong key codes on Mac (but at least the keys generate 
correct characters which is actually more essential for text input). To 
sum it up: you can enter any characters you want, it's just that 
sometimes you have to hit Backspace or Delete here or there to remove 
some garbage.

Gtk:
Well, on Linux some work remains to be done, too. To be more precise, I 
wasn't able to use any dead keys at all, although "pre-accented" keys 
work just fine. I don't seem to be able to configure JP or CN input 
methods on my Linux, so I wasn't able to test the Asian kbd layouts.


I've filed a few JIRAs along my testing. I'll be working on polishing 
keyboard input support on Mac for 8u40. We'll do our best to support 
Linux/Gtk too, but realistically, I expect this to happen some time 
closer to FX 9 on that platform.
