Are you sure that the characters you are entering are encoded
in iso8859-2?   I ask because your Email (that this is a reply to)
arrived here encoded in utf-8, not iso8859-2.

These are UTF-8 characters as displayed here.

This sounds like a problem with your terminal environment,
independent of anything that might be wrong in gnuplot.

I am guessing that you are typing in UTF8, and then when you tell gnuplot
or any other application that it is to be interpreted as iso8859-*
it becomes misinterpreted as some multi-character gibberish.

I agree. But I think those fixes lie outside of gnuplot.

The postscript terminal has supported latin2 and other ISO encodings
for a very long time now.  UTF8 is very recent, however.

The svg and pdf terminals have always supported accented characters.

The new cairo-based terminals, both png and pdf, are natively
UTF8 with internal code to convert from other encodings.

SVG is also natively UTF8.

Why do you say that?  Do you mean that you don't want to use
bitmap terminals for other reasons?  The internationalization support
in the libgd terminals (png/gif/jpeg) comes directly from the
freetype2 library, which is probably the same library used by=20
the other programs on your system, and uses the same fonts as well.
So the support for accented characters through gnuplot's png/gif/jpeg
terminals should match what you see on the rest of the system.=20

caveat:  I have only unsed gnuplot under linux/unix, and have
little idea what works or doesn't work under Windows.
