[Mathlib-develop] umlaute

[bblochl2 <bbl...@co...>]

I would recommend to avoid the special german characters, that always 
get warnings with UTF8.

./jmathlib/tools/junit/framework/TestSuite.java:41: warning: unmappable 
character for encoding UTF8
* Parts of this method was written at 2337 meters in the H?ffih?tte,

More than a dozend of the warnings have the source in ö and ü.
