This is an example of a more general bug that I have not yet been
able squelch in a satisfactory manner.  In enhanced mode, the first
font output to the device in a plot sometimes gets "stuck" as the
default font. Usually this is whatever font is used for the plot title.
But in your example there is no title, so the first font used is for
the tics.

Trivial work-around:

 set title " "      # Single space force invocation of default font

Fix:

I don't know.  I haven't pinned down exactly when/why this occurs.
There is not *supposed* to be any difference in the PostScript
enhanced text processing between version 3.7 and 4.0/4.1
Obviously some difference has crept in.  The bug crops up in other
terminal drivers also; it's not just PostScript.
