dir output does not create UTF-8 chars (Umlaute) - Converter solution available ?

When I enter at the command prompt the well known command

dir >filelist.txt

then all filenames are written into the file. But unfortunately all
special chars like e.g. german Umlaute (äöü) are replaced by other special chars.

How do I achieve that the correct chars are written to the output ?

I could imagine two ways:

1.) dir |convert-to-utf8 >filelist.txt

or

2.) dir >filelist.txt
convert-to-utf8.exe filelist.txt

Does someone know such pipe / file converters ?
