The useflag "cjk" if a2ps creates ps-files with font errors when displayed by gs. Disabling cjk produces a document which can be interpreted by gs. I would expect the useflag to pull in necessary dependencies for Asian font sets. The following error appears when opening a file with gs: GPL Ghostscript 9.21 (2017-03-16) Copyright (C) 2017 Artifex Software, Inc. All rights reserved.

Enable cjk use-flag, emerge a2ps 2. Use a2ps to produce a ps-document. 3. Try opening with gs. Actual Results: Error. Expected Results: Document should be interpreted and displayed without error.
Please try 4.15. What dependencies do we need to add?
It's now working for me with a2ps 4.15.4 and ghostscript 10.01.2, no more errors.
