I have "cp1252.4ht" in MiKTeX\tex\generic\tex4ht
Also a "cp1252.def" in MiKTeX\tex\latex\base

No signs at all of "cp1252.enc" in MiKTek but I do have two copies 
elsewhere - one in Maxima and one in a rendering engine subdir.

Where do I need to put it in the MiKTeX/GNUplot directories please?

You are correct again!

That bit works fine, unfortunately on my rendering engine there is also 
the plaintext of the actual unicode escape sequences sat on top of it.

ie. alpha beta gamma delta epsilon symbols with

\U+03B1 \U+03B2 \U+03b3 splatted on top of it (5! characters worth).

It looks to me like:

Alpha is actually a lowercase a of the handwriting sort
Beta is correctly rendered as the symbol
Gamma is an uppercase X shifted down by one third of a line height
Delta is correctly rendered (but why or how I do not know)
Epsilon is correctly rendered (but why or how I do not know)

I copied your example verbatim first and then added extra spaces to the 
front so that the Greek letters appeared unmolested by the plaintext.

"Alpha" doesn't look much like a Greek alpha to me nor does "Gamma".
Beta, Delta and Epsilon all look fine although where those last two came 
from I have absolutely no idea!

.eps file content looks OK to me so this is another vexing rendering 
engine fault in my Windows version of TeX. It contains the 3 escape 
sequences as above. I will give GNUplot patchlevel 3 a try next.

Thanks again for your very helpful suggestions and patience.
