keyboard in the source code, and at runtime you have a value of type
'String' which contains the Unicode value for an umlaut.
I am confused why that would not work directly? (Though, I have never
used HDBC). It seems to be that the only way to keep things sensible
is if all values of type 'String' *only* ever contain Unicode
chars. If you need a utf-8 encoded 'string' then it should use a
different type -- perhaps a newtype wrapper around a plain old
