fixed: keyboard layout blank and double QWERTY.

There are 3 solutions to this issue

1) @notspiff fix to use a fallback to English with the font13 which is
not what's used elsewhere in skin

2) use the Roboto fonts I was working on and no longer am, but already has
the Hebrew characters added (correctly or incorrectly idk)

3) simple, use English names, since default language is English, users
must have some degree of understanding of that and smart enough to know it.

Since I no longer work on that font , nor speak such languages I was
adding characters for and have no desire to extend it from what is done
atm

This was my solution, both simplest and avoids dealing with niggling issues.
