Compile Errors in OpenJDK 11 with Non-English Characters in Compilation Path

[Magnus Ihse Bursie]

Congratulations! You get to test drive the recently updated build 
instructions for Windows locale requirements! :-)

Please see 
https://github.com/openjdk/jdk/blob/master/doc/building.md#locale-requirements

In particular, I believe you need to set your system locale.

Please report back if that solves the problem or not.
