If the file is utf-8, this is ok with the format build from context standalone
and the lmroman otf
\font\testa=file:lmroman10-regular
\testa
\footline={}
This is an Umlaut Test: öäüÖÄÜß.
\vfill\eject\bye

This one loads the pfb fonts and no umlauts are shown
\footline={}
This is an Umlaut Test: öäüÖÄÜß.
\vfill\eject\bye
