[ Before posting bugs, please check
https://code.google.com/p/hackerskeyboard/wiki/FrequentlyAskedQuestions and
the existing bugs for known issues - my responses may be delayed since I
have very little time to work on this project. ]

What steps will reproduce the problem?
1. Install hacker keyboard
2. Install German layout/dictionary
3. Use 5row layout in landscape and 4row gingerbread in potrair

What is the expected behavior? What do you see instead?
Expected: letters ä ö ü ß should be available in 4row gingerbread layout as 
it happens for other keyboards like samsung swype
Instead: I receive the stand Englush kayout, i.e. excluding umlauts etc in 4row 
gingerbread. These are also not available when pressing shift or symbols. Work 
around is to enter rotate screen so it switches to full 5row layout

What version of Hacker's Keyboard are you using, for example "1.37"? (See
"Debug" section at the bottom of the app's Settings menu.)
1.37.1419 on Android 4.1.2

On what phone or tablet?
Samsung Galaxy S2

If applicable, does this affect the 4-row or 5-row layout, or both? Which
language(s)?
4row German layout, see above

Please provide any additional information below.
I really like that there is an easy way to switch between full keyboard and a 
more smartphone like keyboard. It means that one can use hacker keyboard all 
the time, rather them switching between input modes. As described above thid 
works for English but not German as some very common letters are missing in the 
moment. Itwozld be really awesome if these could be added.

Thanks for all your hard work!
