I am not aware of any such problem in gnuplot, but without seeing the 
input commands I cannot comment on whether something may be incorrectly
specified to the program.  If you want to pursue this, please upload the
scripts to the Bug tracker on SourceForge:
   https://sourceforge.net/tracker/?atid=102055&group_id=2055

In general, gnuplot leaves font handling to the operating system.
So font problems probably indicate system configuration problems.

# xlsfonts | grep -i helv | wc
    320     320   19172

On my machine x11 offers 320 variants of helvetica, some from Adobe
and others from URW.

I can guarantee that this works correctly inside gnuplot.
Of course, if your system doesn't really have those fonts installed.....

I suspect it is neither, but instead an issue with the local system
font configuration.
