Ruby

On Windows, non-ascii drive letters are allowed for virtual drives. Some Ruby methods do not seem to handle this well.

subst ä: C:\tmp\ 

File.absolute_path?("ä:/") #=> expected: true, actual: false File.write("ä:/foo.txt", "foo") Dir.glob("c:/tmp/*.txt") #=> ["c:/tmp/foo.txt"] Dir.glob("ä:/*.txt") #=> expected: ["ä:/foo.txt"], actual: [] Dir.entries("ä:/") #=> [".", "..", "foo.txt"] 

It would be nice if someone more familiar with Windows could do a more comprehensive investigation and write a patch.
